To answer any questions related to vehicle legislation in the US, look no further than the "Big Three": GM, Ford, and Chrysler/AMC/DaimlerChrysler/FCA/Stellantis.
These three dipshits bitch and moan incessantly to daddy government any time they have to contend with actual competition. Look at Japanese kei trucks for the most recent example. Some states are even outright revoking their registrations despite being 100% legally imported, inspected, insured, and licensed. The excuse is "they are unsafe", meanwhile states will happily register Bubba's '32 Ford with a SBC, no mufflers, no cats, no seatbelts, headlight output equivalent to 3 candles, a single brake light, and no actual structure besides "pretty metal". But kei trucks bad. Because safety.
