Imagine if either of the ladies were injured, there would be a lawsuit against the bus line, the bus driver and the guy who hit them - there's probably someone at the bus line drafting a memo saying drivers are to never do this sort of thing.
I think he should be commended for his kindness - the world could use more people who go out of their way for others - and hopefully his injuries heal quickly and the ticket is thrown out by a compassionate judge.
