I had a funny little idea while playing that would make a cute little easter egg. When you crash the bus and damage the marquee, it should change the texture/text on there to say something like "ouch!" instead of just breaking the glass. On the smaller displays, there should be a something like a little face with the eyes "X"'ed out. It's personal touches like these that make me love games, you don't have to be serious all the time!
BeamNG is a "dynamic soft-body physics vehicle simulator." It would look stupid when trying to create a realistic crash. Dev's do add easter eggs once in a while though, but I don't think there should be a permanent easter egg like that.
