I think it would be good if the arrow showing you which direction to go in was actually on the side of the screen towards that location. Like if you had to drive to a location to your left, the arrow would be on the left of the screen. Also, sometimes it's hard to see which part of the bus is the front, it looks the same at both ends..
Just driving around running over street lights and benches and things is fun. It's a shame the bus-looping feature is broken, that would definitely have made it even more fun. Good sound effects with the engine, screeching tires, and smashing into things.
