Don't bother trying to pass. Only pass when you know you can.
If you think you are a good driver, then you must drive a lot. If you drive a lot, remind yourself odds are against you for avoiding an accident. Pay attention.
No one drives like you.
Don't hit anything...anything.
Blinkers are a tool. Don't use because it's the law, use them to your advantage. Also, don't use them to ask to make a maneuver. You either can or not, and blinkers will help others become aware of your intent.
If you tailgate, I know you do not know how to drive because you are assuming the other driver is as good as you.
