Either the guy is deficiant somehow and crosses improperly in a busy intersection or there is a traffic regulation issue with the lights at that section or something. In the first case, it's still a hit and run and the driver's history. In the second, I hope his family wins a mint since the traffic regulation issue was not resolved after he(and probably others) had incidents there. Given that a bus driver would hit and run, I'm banking it's more an issue with #2.
As for the bridge guy:

...that's like the worst nightmare come true. I feel for the guy since how many of us have stood there going...ooh, look at me, but didn't bit it and actually fall. doh!
