But yes, what you say is the logical consequence (except I'm not kidding about grief and impatience).
My point really is that if we want our kids not to get horribly injured or killed, we can't just focus on "other people" making bad decisions like driving drunk. We have to acknowledge that we've collectively built a system that requires people to put each other in danger with cars, and we have to think about how to change that. Cars bring a lot of benefits like autonomy and decentralization, how do we keep that but kill fewer people?
