It may not have been intentional hit and run. Not that it makes it any better. I saw a bus swipe a pedestrian once. Thankfully the guy wasn't hurt, but the bus driver just kept going. It was the back end of the bus and he didn't even realise he had hit the guy. That's the problem with those bigger cars. If its at night and dark, or you're not looking, you can hit something smaller and you're so big you don't feel the impact
