Fired Up

Today I was heading eastbound on a busy highway and noticed that the westbound traffic was quite backed up. The culprit? A police car who had pulled over an old pickup truck with massive photos of an aborted fetus and a giant sign that read 'ABORTION IS MURDER!'

Clearly this truck (who I had seen once before outside a local planned parenthood) wanted people to stop and look at this disturbing imagery.

So here's my question: If a rubber necker who was looking at this truck got in a wreck and died as a result of it, what would that be?
