Homicidal Bus Driver?

I was crossing the street with a walk signal this morning, and got a nasty look from a bus driver that screeched to a halt just before I walked in front of him... I'd been looking at him nervously, and pausing to see if he was really going to stop.

But he did, so I hurried past, and just after I got past, he slammed on the accelerator and lurched out into traffic, before finally realizing that he had a RED light and slamming on the brakes, ending up blocking both directions of cross traffic, except for a slow trickle that was able to swerve around him, until his light finally turned green.

Gah.
