There also clear lack of alcohol enjoyment education. Gather at friends place and stay overnight, carpools and draw a sober Sam, don’t get overdrunk and drink water for the last 90 min of the party, etc…

I do agree infras and density is a better option. But lack of infra doesn’t justify to drive drunk.

I’m not justifying drunk driving. I asked how California is different from other states in this regard.

Unless you're wealthy enough to live in the core of a major metropolitan area, it's all of the states.
