I was kinda shootin' towards the abolition of personal vehicles altogether, or at least relegated to that of "sport only", such as NASCAR and drag racing or if one likes to take the ATV out...it no longer becomes a family necessity.
No more road construction, more vehicles to go to recycling plants...and in their place, electro-magnetic rail on all major throughways and biways. And let the American fatasses walk the half mile or so to the local train station....America's too fat anyway.

personal vehicles can come back when technology makes one that is pollution free and affordable
