There are dozens upon dozens of designs that permit bump crossing. I've seen robots with 10" wheels cross the bump, I've seen robots with 3.5" wheels cross the bump. Some glide over like it's nothing, others slowly and carefully get over, and some just force it through. But there isn't much reason not to cross the bump. I can think of more than a few scenarios where crossing the bump could easily be the difference between winning or losing.
