Where did I say the seatbelt law doesn't save lives? I just said it was essentially unenforceable, and generally tacked on when a driver gets pulled over for - let's say speeding.
Making something illegal can save save lives, but it takes more than just that.
if a cop sees one on a cell phone, they could pull them over. cops due drive on the streets with other cars. if I can see people driving and using cell phone, the cop can as well
how is that unenforceable?
