99% of the "accidents" that occur in these instances are 100% EASILY avoidable!! For instance:
1. Don't tailgate...it doesn't take a physics major to know that you will NOT stop in time, no matter how fast your reaction times are, how fancy your tires are, or how many speedholes your rotors have.

2. When there are 2 lanes that turn in the same direction, why do people feel the need to sidle alongside the car next to them? Can't people understand that most everybody on the road is incapable of reasonably maintaining their lane?

3. Why do people wait until they are 3/4 of the way down a merge/exit lane before signaling? Turn your F'n signal on BEFORE parallel traffic can see you to at least let people know your immediate intention.

4. If you're first in line stopped at a red light, I don't care how green the light turns...do yourself a favor and look both ways before entering the intersection. It costs you nothing to do so.

5. If you're on a multiple lane road and a lane on either side of you is completely stopped...don't go driving at some insane speed just because your lane is clear. You can almost always count on a car coming from the opposing direction being let in by stopped traffic asking to get t-boned.
