Nah, the NHSTA has this weird idea that if you are more visible to other motorists than that's a bad thing. Any useful (and awesome) safety feature to do with lights and the NHTSA gets all butt hurt about it.
Hmm this is true. Nonetheless, I'm keeping my fingers crossed that it sneaks it's way in for the US.Perhaps:
a. It's a global vehicle; so perhaps it to accommodate for both left and right hand drive?
b. Aesthetics (symmetry)?
