How about alcohol odour detection required in all vehicles? How about attention-distraction monitoring, and perhaps first penalty or safeguard is forced reduced speed, where attention-distraction level determined determines the maximum speed the vehicle can go - whereby reducing the need for as fast of a reaction time? Any other possible solutions? I think in general coddling people is more harmful than good, and is lazy to not find nuanced solutions - just because blanket rules are "easier."
