curious reaction tho, meaning getting off the bike & standing in the lane. I'd think you'd rather start pedaling faster to get out of his way?

I had a weird stop once. was riding a paved bike trail, came to a road crossing. the crossing light wasn't with me, the cars had a green. but 1 car stopped. normally I would not proceed but rather wave them on with another thank you wave. I think I remember trying that but they still didn't move. so I started across but another car coming from behind him just went around him at the same time I was in the lane(s). that car stopped, I stopped, then I rolled my bike backwards awkwardly. I should have known better
