I'm glad you weren't hurt worse; an unfortunate college student at my university tried the same thing with a public transit bus stopped to let her off at a green light, and she did not survive.

The car passing the bus had no chance of seeing her, and there was no reason to believe anyone would be crossing against the green light. I think she may have had a pattern-match malfunction and acted as if she'd just disembarked a school bus. It was a tragedy all around.
