The number of instances of people violating DUI law in order to move vehicles around private property probably or other similarly benign cases outnumber real drunk driving 100:1.

Furthermore, the habitual drunks who actually pose a danger to public health are already playing the "drive a $1k car registered in someone else's name without a license" game so this won't affect them for ~20yr even if it's implemented tomorrow and based on the legislation it looks like it'll be years before anything actually gets implemented in new cars.
