I understand about the handling, I still have my motorcycle license even though I have not ridden in quite a while. I will not try to maneuver the beast I drive if someone is trying to pass me at a very high speed differential - I always figured that motorcycles, police cars, ambulances or whatever that go that fast know how to get around slower vehicles.
If somebody on a bike is flying up behind me, he will be past me before I see him. Again, a Dodge Ram 2500 with a cap has lousy visibility looking backwards. BTW, if you zoom past me I am more likely to shake my head and say "future road pizza" than flip you off ;-)
