Oh man, that sucks--he fouled up your whole morning, which had started out so nicely. Here's hoping you'll have some better commuting experiences in the future.

I'm sure I wouldn't have thought of this at the time it happened if it were I it happened to, but it sounds like the jerk left the scene of an accident. I mean, he did hit you, though only marginally. Think about what would have happened if he clipped another car and then drove off. Not that there's anything you can do about it, maybe just something to consider in the future--though hoping it doesn't happen again.

I hope your day gets better from here.
