Think about how you feel safer in that giant SUV compared to a subcompact. Then remember the bus is significantly larger than the SUV even comparing the SUV to the subcompact. Which "wins" in the accident? Now think of the light rail train, even larger than the bus.
I'd rather not even have to be in the path of a drunk driver in the first place. Maybe we could redesign our cities ahead of time so those drunks could walk or ride the bus or bicycle instead of getting behind the wheel. Impossible, I'm sure.
You seemingly can't even imagine a world where one doesn't need to get in a car to go to a bar or go get groceries, it's just assumed both of these people and you will have to be in a car and share the path.
Once again you haven't actually logically thought about these differences. Think about it again before you reply.
