I got 6 points on my license in a few month period and had to go to defensive driving school when I was still in my early twenties. Ever since, I've been real careful about how I drive. I use my turn signals 99.9% of the time and usually with plenty of warning before I turn. I make sure I come to a complete stop at a stop sign. Even if I don't see any other cars around I still think it could be a trick by some cop with a vendetta, so I stop for a full second or two. I do speed like I stole something when I am in a really big hurry, but that doesn't happen as much as it used to.
