I've made bad judgement calls and I'm sure I'm not the only one.

Sometimes there are people who want to let you know about it. This guy was a lot more persistent than necessary but I understand where he's coming from. Ignoring crosswalks is a pet peeve of mine. I witnessed the aftermath of a cyclist/car collision in a bike/ped crossing. The driver wasn't paying attention.

It's quite possible in your case though that the driver just had some sort of axe to grind. Learn from it and move on. If you feel it's too dangerous to obey traffic laws in that area you might need to change routes or leave alot earlier to avoid some of the chaos.
