Fun Fact: I had actually implemented a pretty complicated system that allowed the pedestrians to stop if they are going to walk into your car, as well as stop if they get too close to the pedestrian in front of them, and pause spawning more pedestrians in that row if it's backed up. It all worked pretty well. Then I realized that it kinda trivialized the game, as you could just slowly creep forward and everybody will stop for you, so I ended up deleting that whole system.
