I think we owe it to the next guy to attempt to make an impression on these people in an effort to get them to think next time.

I always think of what might have happened if it were my less experienced wife in the situation rather then me.

Just yesterday I was waiting at a redlight. I could see the light for the other direction turn yellow then red as a guy went through. No big deal really as you have to expect that last guy trying to beat the yellow. The next guy however, who sped up to about 45 (in a 25) in order to flat out run the solid red got my attention!

I got his attention at the next intersection and told him in great detail what would happen to him if he killed anyone I knew pulling that stunt.

Maybe it won't have any affect on him, maybe it will. You have to at least try though.
