@hawkeye10,
What fantasy world do you live in?
Drivers are supposed to adjust their speed for weather and visibility conditions. You are supposed to have your car under control at all times. Your stopping distance can't exceed your line of sight, and speed must be adjusted accordingly. And you need to keep a certain distance from other vehicles ahead of you, be they cars or bikes, so you can stop without hitting them if need be, and speed must be adjusted accordingly.
That has nothing to do with the law--it's common sense if you want to avoid running into another car, or a bike. And that's how I drive. It's the way I've been driving since I was 16. So some real humans actually drive responsibly.
Swift just found out a car is a lethal weapon--it's got to be operated with care, in a responsible manner. And you really can't do that when you're drunk. He just found that out too.
