Pennsylvania teenager shot in road rage incident

[Igel]

2. To provoke the guy (if it was a guy)?

Lots of things.

To merit being shot, much less killed? Nothing, unless she was actively trying to kill him and he had no way out.

Lots of empty road in that picture, so he had a way out. If PA drivers are like Houston drivers, they don't see empty road behind that's just a tap of the brakes away from being accessible. The only space that counts is what's in front of the driver you're next to or that space way up ahead of you, and too many people race to keep from having somebody move into that space and too many race to merge in front of the person in the car next to them. To touch the brake to slow down in order to merge is humiliation. Merging drivers have to yield right of way.

Notice I speak much less of "cars" and much more of "people" and "drivers." Dehumanizing them makes doing stupid, risky, dangerous things easier.
