I think that the new blindingly bright headlights play a large part in the massive upswing in nighttime deaths. I have pretty much given up driving at night. Practically every vehicle coming the other way blinds me for at least 20 seconds. I was driving purely by watching the outer lane marker on the ground to my right. It's just too dangerous to continue. Don't even get me started on the morons in lifted trucks that get 10 ft behind you and blast all 3 mirrors until you can somehow, without being able to see, get out of their way.

It's often because people line up their car according to the car next to them. If one person does a lousy job and the next person copies them it begins to spread like a virus.
