YES. It bothers me SO much. I've seen dogs ride on top of the large tool boxes some people have in the back of their trucks. WHY!?! would someone let ANYONE ride like that.

Something could fly into their eyes, they could jump out, they could ram against the side of the truck and break something. It's totally NOT safe. Not that riding inside the cab is completely safe but it's a lot more secure that riding in the bed of a truck.
