in the U.S there seems to be a hatred of pedestrians among the driver class, and a tendency for police to let even the most egregious drivers off the hook when a pedestrian gets killed (as long as it's not a hit and run), therefore this does not seem a good strategy.

However, and this is if they are in the U.S, perhaps they are mildly suicidal and thinking that if they get run over and killed it lets them off the hook for suicide and whoever ran them over gets a few problems which just serves those jerks right.
