Things I learned from daily driving...
1.) Don't be in a hurry and drive like an ass, it doesn't really benefit you or anyone else. You eat up gas and money and if you do the math, arriving at your destination 2 minutes sooner probably isn't worth it.
2.) Expect everyone else to drive like an *******. Expect that people will cut you off without a turn signal. Expect that people will slam on their brakes as soon as they see brake lights because they are too busy texting to know what is going on. Expect that people will slow down, gawk at an accident, and likely cause another one. When it happens you aren't surprised or unprepared and can react calmly and appropriately.
3.) Don't get upset and angry while driving. They can't usually hear you yelling. Even if they can they won't care and won't change. It's easier on your own health to refer to #2 and just accept the fact that the world is full of idiots with a license to drive.
