Basically, and I hate to say it, he was acting like a big baby. Taking a

that I intimidated him, I'm don't look that imposing, but if I didn't know
better I'd have thought he was scared.

&*^$ bicycle, riding in the left lane, and his souped car can't even outrun
it (at least not permanently). Scary, very scary. You done disgrace to his
manhood, and then confronted him (twice). His ego may never be the same.

I'd have phoned his plate to the local drunk driver/road rager hotline,
just to report general erratic and inept behavior behind the wheel.
I wonder how much an armed cop would scare this clearly unbalanced chap.
