Defenders of the empathy theory might insist that the windshield has
some effect on our ability to empathize with another person, thus contributing to the road rage phenomenon. The windshield creates distance between people, much like a computer screen does, which is why we have so much nasty behavior online. Road rage may be reactive, but a lot of online trolling seems to be unprovoked. There are people who troll just for the fun of it—albeit it a sick, sadistic fun. Surely that's a case where it's all about dehumanization?
