Many of the reasons cars are so expensive are because of federal mandates to car manufacturers.
Since some states are now considering laws that guns and ammunition manufactured and used exclusively in their state cannot be regulated by the feds, a good question is whether the same idea could be applied to cars?
That is, if there was a state law that as long as cars were made according to state rules, they were legal except on federal highways, what kind of vehicles would you get?
Most states would likely require safety glass and seat belts, but not a whole bunch of other expensive gear, such as airbags, black boxes, and depending on the vehicle, not even a catalytic converter. They would most likely get much better mileage, and ironically, be much safer than by federal standards.
Oh that would be great.
There’s already 70 types of gasoline required by the EPA and we see the problems that causes.
Wouldn’t it be fun for the mfgrs to design and homologate 50 different version of cars for each state?
