There are Uber, taxi and other public transportation. You can get high with your friends and don't drive. Just plan ahead.

This.

If you are drunk, high, tired af, or just sleepy, stop being a danger for others. A car is a hunk of metal going at high speed, stop being a child about it.

Fix the system, because you cant fix the people

In the city yeah, I believe most drunk driving accidents happen in places and times where uber would be too overpriced or public transport too inconvenient
