Pigeons and human have a pact. You continue and they will fly away in the last second. Cars don't need to stop for pigeons.

I hope you're kidding. In an area where they had just opened a freeway segment for my commute, my car had a couple of "reverse bird strikes" -- the car was safe but the fate of the bird was unknown -- at the beginning of the new segment. It's possible the birds weren't pigeons.
