Are any of these cars available outside the US? From what I've been able to tell, US regulations are much weakest in this regard which is possibly why there are so many words cars there.
(In some aspects the US automotive regulations are actually stricter than in Europe. For example, in Europe there are some vehicles (eg: Audi) where the wing mirrors are replaced by screens/cameras, but this is not permitted in the US. Adaptive matrix headlights are also not allowed in the US.)
