I have seen these on the roads out west...like in AZ...so cool

Colorado’s Division of Motor Vehicles also tried to explicitly ban them last year, though it later pulled its proposed rule. Some kei vehicle owners, however, say the state is still trying to keep them off the road by refusing to allow them into the emissions testing process.

As usual it's confusion from news when reporting on public policy. So are they proposing that there be exceptions to emissions rules for these vehicles or not? Because that will make a huge amount of difference in how much I or pretty much anyone else should support this.

To be fair, they’re death traps at most American road speeds, especially if there’s an American vehicle involved. The smart was the only kei-grade car allowed in North America and it was not too popular (the price didn’t help).

But smaller cars is a great idea.

Probably not on interstates. But for most roads it ought to be okay.
