Sure, if you can't pass and there's someone in front of you going slow, it will force you to slow down. Most injuries and deaths by car in SF are of people out

Sure, if you can't pass and there's someone in front of you going slow, it will force you to slow down. Most injuries and deaths by car in SF are of people outside of cars, and I suspect that the drivers who maimed/killed those people were usually in front / catching up, not following someone at high speed and had their victim jump between.
