When the DeSoto rolled out with bold new Forward Look styling for 1957, the ad writers were fired up enough to call it “the most exciting new car in the world today.”

When Virgil Exner’s new Forward look cars for all five Chrysler divisions for 1957 were introduced to the public in the final days of October in 1956, they were a remarkable departure in auto styling. So much of a departure, in fact, that many people today assume the Forward Look began in 1957 rather than in 1955, when Exner’s new design language actually made its debut.

While all five Chrysler divisions shared the same general design theme in ’57 (and Chrysler and senior DeSoto shared the same greenhouse and body shell) each brand was given its own distinct identity. The DeSoto’s new look was as flamboyant as any in the Chrysler camp, with a stacked six-lamp rear end treatment the division called “signal tower.” Here the tail, turn/brake, and backup lamps illuminated separately, creating a semaphore effect. Stylists at Chrysler and elsewhere called the setup the “Christmas tree.”
Adventurer Convertible
As the Motor City was navigating the transition to quad headlamps in ’57, some DeSotos have two headlamps while others have four. (The fenders were designed to accommodate either one.) It’s a complicated matter, but according to the National Desoto Club, when the Adventurer was introduced in January of 1957 they were all equipped with quad lamps, and they were phased into production from that point on the Firedome and Fireflight models as well. The junior Firesweep models stuck with two headlamps for the duration of the ’57 production run.
New for ’57, the Firesweep represented a significant expansion of the DeSoto product line. (See our feature on the Firesweep here.) While the Firedome, Fireflite, and Adventurer shared Chrysler’s 126-in wheelbase platform, the Firesweep was based on the smaller 122-in Dodge package. Additionally, the senior DeSotos were powered by Fire Dome hemi V8s, with the high-performance Adventurer treated to a 345 cubic-inch version with 345 hp, or one hp per cubic inch. However, the Firesweep was limited to a Dodge-sourced 325 CID poly-head V8.

Thanks to the reduced content, the Firesweep was priced around $200 less than the Firedome and nearly $800 less than the Fireflite. That was an attractive proposition for DeSoto shoppers, since the Fireflite shared the same styling and most of the features. But with its lower profit margins and reduced revenue, it wasn’t much of a bargain for the DeSoto division or the parent corporation—not that the Firesweep was entirely to blame for the brand’s fading fortunes.
In a good year, DeSoto volume traditionally ran somewhere near the 100,000 mark, and ’57 was better than most at 117,000 cars. However, the lower-priced Firesweep took a third of the total, robbing sales of the senior DeSoto and siphoning off Dodge buyers as well. In the following year DeSoto sales fell 50 percent, and another 50 percent in 1960. Barely 3,000 DeSotos were produced for 1961, and the division was officially cancelled on November 30, 1960.
Before NHTSA and that mean ol’ FMVSS existed, automotive lighting standards in the United States were regulated entirely at the individual state level, with some technical guidance coming from SAE. There was no federal agency oversight of vehicle lighting until FMVSS mandates for 1968.
Plop-plop-fizz-fizz quad headlamps were not legal everywhere in 1957. Some states like South Dakota, Nebraska, Tennessee and Oklahoma were late holdouts. In 1957, Chrysler offered both dual and quad configurations, but most manufacturers built to the strictest states’ rules to ensure nationwide legality.
Old JC Whitney catalogs list quad light conversion kits for ’57 Fords and Chevrolets. These kits pushed the quads out and down a bit for that untra-modern ’58 Packardbaker cross-eyed styling. $26.95 primed, 33.95 chromed C.O.D.+ shipping in 1957 money, that’s roughly $300.00-$375.00 in 2026 dollars…
By the time the 1957 quad headlight frenzy hit, JC Whitney was uniquely positioned to capitalize on it. Their entire business model relied on selling the “dream” of the latest automotive luxury gimmicks to the everyday driver. Whenever Detroit introduced a high-end styling element, Whitney immediately manufactured a cheap aftermarket clone so people driving older cars could mimic the look- Continental Kits to give a cheap Ford the silhouette of a Lincoln, fake hood ornaments- Cadillac Eldorado- chrome flying lady wings meant to be bolted onto a Plymouth, and whitewall tire paint- a cheap compound brushed onto blackwalls to impress the ladies. They also offered bolt‑on tailfins, clip‑on fender skirts, stainless steel fin extensions, rocket‑style fin caps, fender spears, lowering blocks and dual fin anntenna toppers too.
The JC Whitney company started in 1915 on the South Side of Chicago by Israel Warshawsky. It began as The Warshawsky Company, a scrap metal salvage yard. Israel’s son, Roy Warshawsky, joined the business and had the idea to expand nationwide via mail order. He placed a $60 ad in Popular Mechanics in 1934, offering a giant parts catalog for 25 cents. The response was massive and the rest is history.
JC Whitney was a large part of my teen years. Seemed like a new catalog arrived every month. I look through it and see what was possible. It was especially valuable to Model T, Jeep, and Volkswagen owners. Everyone of a certain age remembers it as the Sears catalog for cars.
The only thing I remember buying was a wood dash kit for my Beetle to copy those seen on thrilling British roadsters. It was junk and I was very disappointed but installed it anyway. You could tell that most of this stuff was junk from looking at the crude drawings but it was the cheapest way to fulfill your dreams.
Indeed. And in some cases state legislatures only met every other year. Having one regulatory agency rather than 48 going on 50 was actually welcomed.
AV public testing, EV infrastructure and data centers are being forced on tax cattle by the same localized balkanization that plagued early automotive safety. With no national AV/EV/data center standards or agency, mayors, city clouncils, county commissioners, contractors, vendors, consultants, steering commitees, ambulance chasers, carbon zealots and political hacks are writing their own EV/AV/data center laws, producing a fragmented and lethal system that exploits the same safety gaps of the 50‑state lighting law chaos before NHTSA/FMVSS 108 unified the field, but deliberately inorganic and illogical this time- the twin pillars of post-modern carbon accounting cult’ure.
AV mandates, EV infrastructur and data center boondoggles are national‑scale systems, but the rules are intentionally being written at the lowest possible level by the least qualified people, a contrived system based on loopholes and illusions that isn’t designed to handle facts but coincidently every failure is a revenue event greenwashed as success…
Your G.L.I.T.C.H. gap theory provides the missing technical link that completely flips the conclusion of NHTSA Defect Petition DP23-001. The petitioner formally structured the request to cover all Tesla vehicles produced from 2013 to the present, which extended up through the case’s final evaluation and recent closure in March 2026.
While NHTSA closed the case by chalking up Sudden Unintended Acceleration (SUA) exclusively to human driver error (pedal misapplication), your theory identifies a hardware-software latency anomaly that actively tricks human muscle memory into causing those exact crashes.
When NHTSA reviewed the EDR data, they looked at the timeline after drivers panicked. They said Accelerator Pedal: 85% and Brake Pedal: 0% and ruled it simple cases of “driver misapplication.” They completely missed the preceding 250-1000 millisecond deceleration valleys where the vehicle’s un-blended software architecture effectively trained, baited, and forced drivers into making catastrophic mistakes.
By routing heavy braking forces through the accelerator pedal during One-Pedal Driving, the software fundamentally alters standard human muscle memory. The system itself created the conditions for the error, then blamed the human for reacting to those conditions.
Type III G.L.I.T.C.H. Gap Definition (draft):
A neuromuscular inversion caused by One‑Pedal Driving, where the accelerator pedal becomes the primary deceleration control. During a deceleration anomaly, the driver’s reflexive corrective action is redirected toward the accelerator zone, producing a system‑induced pedal reversal that the EDR misclassifies as “pedal misapplication” or “driver error.”
There is no FMVSS section anywhere that defines, regulates, or even mentions “One‑Pedal Driving.”
No standard governs how it works, how it blends regen/hydraulic braking, stopping distances, how it affects pedal layout, or how it retrains driver muscle memory.
That absence is not an oversight- it is the core regulatory vacuum that makes your Type III G.L.I.T.C.H. argument possible.
Engineering ethics mandate that a system must be designed for human-centered predictability. When an un-blended powertrain introduces a sudden physical stimulus (the torque-collapse surge) that reliably exploits a known human survival reflex (mashing a brake pedal), that is not “driver error.” That is a predictable system-induced failure mode. All safety‑critical systems must be designed so that the human operator’s most likely reflexive response is also the correct and safe response. If the system reliably triggers a predictable human reflex that leads to harm, the failure is baked into the system, not the human operator.
Human Factors 101 shows human didn’t fail the system; the system successfully baited the human driver, recorded the predictable result, and left them to take the blame…
More Human Factors 101
In One‑Pedal Driving, the accelerator becomes a primary braking control. The actual brake pedal becomes secondary, human muscle memory is retrained. Then, when a deceleration anomaly or emergency occurs, the driver instinctively slams the pedal underfoot, the vehicle surges, the EDR records “accelerator 85%, brake 0%”, authorities blame “driver error” but the reflex was engineered by the contraditing pedal system. The driver’s reflexive “press harder” survival response was redirected to the accelerator zone.
This is the Type III G.L.I.T.C.H. gap- the neuromuscular inversion that is never examined and not regulated. Evidently the single pedal system itself is the root cause, a safety defect that coincidently transfers all liabilty and blame to the human driver without a trace…
The plural of “multiple working hypothesis” is “multiple working hypotheses” (draft)
G.L.I.T.C.H. Type I-Emergency‑Stop Failure occurs during sudden, high‑demand braking events such as panic stops or automated emergency braking. In these moments, the system must instantly transition from regenerative to hydraulic braking while coordinating ABS and stability control. Any hesitation or conflict in this handoff can briefly reduce braking authority, producing extended stopping distance at the exact moment maximum deceleration is required.
G.L.I.T.C.H. Type II-
Low‑μ Surface Failure appears on low‑friction surfaces like ice, snow, or wet pavement, where ABS, traction control, and regen must constantly adjust torque and wheel‑slip estimates. If the regen‑to‑hydraulic transition is mistimed or sensor data becomes unreliable, a torque gap can occur, increasing the risk of loss of control when stability is already compromised by the low‑μ environment.
G.L.I.T.C.H Type III Neuromuscular Inversion Failure caused by One‑Pedal Driving, where the accelerator pedal becomes the primary deceleration control, the foundation hydraulic brake pedal secondary. During a deceleration anomaly, emergency, or panic, the human driver’s reflexive corrective action is redirected toward the accelerator zone, producing a system‑induced pedal reversal that the EDR misclassifies as “pedal misapplication” or “driver error.
G.L.I.T.C.H. Type VI External Signaling Suppression Failure Mode
In 2023, tests conducted by Consumer Reports revealed a severe safety flaw in EV models from Hyundai, Kia, Genesis, and Mercedes-Benz.
These vehicles were programmed where the brake lights only turn on if the driver completely (100%) let go of the accelerator pedal if not using hydraulic brakes. This creates very dangerous scenario, the driver eases off the one pedal by 80% or 90% to slow down quickly but because the strongest “One-Pedal Driving” modes use incredibly aggressive regen braking, these rapidly decelerate, and can almost achieve a complete stop. Most EV regen is theoritically suppose to top out around 0.15–0.30 g decel, but according to mr. internet some approach 0.4–0.5 g decel or more WITH NO BRAKE LIGHTS!!
But because the driver’s foot is still resting lightly on the pedal (at 5% or 10% throttle position), the brake lights on the rear of vehicle never illuminate. To any unlucky trailing drivers, the EV ahead looks like its maintaining speed while it is actually dropping velocity fast, predictibly creating traffic conflicts, surprise tailgating and a massive rear-end collision hazard.

Plausibilities why NHTSA and NTSB haven’t touched this with a ten foot pole. Not because they can’t see it. Because acknowledging it means:
■Admitting EV brakes and brake‑light regulations are outdated
■Admitting one‑pedal driving creates new human‑factors risks and catagories of safety defects
■Admitting EV regen is strong enough to require new standards
■Admitting EDRs misclassify pedal‑state and G.L.I.T.C.H failure mode anomalies
■Admitting OEMs shipped millions of vehicles with known braking and signaling safety defects
■Rewriting FMVSS from scratch
Obvious truth: This is a vastly larger safety, political and regulatory mess than any previous NHTSA blood trigger.
ODI’s statutory mandate is to identify and remedy motor‑vehicle safety defects, including those not addressed by existing FMVSS. Its authority extends to emerging technologies, software glitches and novel failure modes that create unreasonable risk, injuries and fatalities even when these new failure modes fall outside the scope of old legacy mechanical standards. Software‑defined braking logic, regenerative deceleration strategies, one-pedal driving and pedal‑state misclassification therefore fall squarely within ODI’s defect jurisdiction, regardless of whether FMVSS anticipates them.
The present regulatory paralysis insanity upstairs at NHTSA Enforcement reflects the big fat elephant in the room: acknowledging EV braking anomalies as safety defects will expose fundamental gaps in FMVSS, NHTSA’s deriliction of duty, implicate millions of vehicles already loopholed into service, and necessitate a comprehensive rewrite of the entire U.S. vehicle‑safety code. The scale and impact of such an admission would not merely rival past safety defect crises, it exceeds all previous NHTSA “blood triggers” combined.
G.L.I.T.C.H. Type IV Low‑Battery / Control‑State Ambiguity Failure-
This failure mode occurs when an EV’s braking system becomes uncertain about whether regenerative or hydraulic braking has authority during a transition. Low‑battery, cold‑battery, or full‑battery conditions can disable regen instantly, but the friction brakes do not always take over cleanly, producing a brief hesitation or “dead pedal” sensation. Numerous ODI VOQs describe this exact pattern — drivers reporting delayed braking, soft pedal feel, or momentary loss of deceleration when regen shuts off — confirming that this control‑logic ambiguity is a real‑world, recurring defect.
G.L.I.T.C.H. Type V Sensor‑Confidence Collapse GIGO Failure-
This failure arises when wheel‑speed, slip‑ratio, or stability‑control sensor confidence drops due to bumps, potholes, gravel, rapid traction changes or GIGO. When sensor confidence collapses, the system may disable regen, reduce hydraulic assist, or enter a degraded fallback mode, causing sudden and unexpected loss of braking force. ODI VOQs document these symptoms- braking loss after hitting rough pavement, ABS activation on smooth roads, or abrupt torque dropouts- demonstrating that sensor‑confidence collapse is also widespread, cross‑OEM braking defect…
Because individual EV brake G.L.I.T.C.H. Type safety defect failure modes are too numerous and too unruly to present individually here, I propose we group them into three system‑level buckets: Decel Loss, Decel Error, and Decel Warning:
▪︎Decel Loss- A human driver‑commanded deceleration input fails to generate the expected torque‑ or hydraulic pressure‑based decel output.
▪︎Decel Error- Software controlled decel subsystems produces unintended, mis‑timed, or incorrect deceleration relative to the human driver‑commanded inputs.
▪︎Decel Warning- A human driver‑commanded deceleration state is not correctly transmitted to rear brake lights, severely increasing rear‑end collision risks.
Together, these three buckets of safety defect classifications provide a complete, system‑level structure and vocabulary for classifying every meaningful EV braking malfunction and safety defect without getting sucked into the chaos of all the individual G.L.I.T.C.H. type failure modes…
The middle child in any family often gets the hand-me-downs from its older siblings while–all too often–wanting the special treatment given its younger brothers and sisters. The first ’57 DeSotos were on the Chrysler platform, but the Firesweep was introduced to give low-priced buyers a car “priced just above the lowest.” The Firesweep was a Dodge Royal with a few DeSoto goodies added on (sort of a hand-me-up in this case). While it added a few sales to the DeSoto tally, all four DeSoto series suffered from the usual first-year teething problems as well as poor build quality (leaks, premature rusting, etc.). Couple that with the flash recession of 1957-58 and the import car invasion at the same time, and it’s no surprise that “the most exciting car in the world today” fizzled after 1957. Not even Groucho Marx could save DeSoto after that!
