I'm NOT "tailgating", I can see you are having trouble maintaining speed IN THE FAST LANE, I'm just trying to HELP by giving ya a PUSH, dang nab it.
My guess, though, in that photo, is that someone decided *not to* make a run for the yellow at the last second (it's at a traffic signal) ... and everyone behind them *was already* on the gas to make that run ... when the lead car's driver decided to stop instead ...
