its a cool conept but i dont think it could ever work. What if the bus wants to go straight when a car wants to go right? and getting into an accident and hitting the guard rail freakin sucks, getting into an accident underneath this thing would really blow. Then you got the issue of decreased visibility when the bus passes over you because its going to get dark under there but that really depends on how big the bug is. It would be cool if it worked though because i hate driving behind a bus in stop and go ciity traffic to have it stop for 5 minutes waiting for someone to come.
