The rest of the lanes are also often moving slowly through that section just due to traffic volume. This is what happened in that video: the driver accelerated slightly and started passing cars once in the exit lane (nothing to do with negotiating with entering cars). If this theory is correct, then presumably you’d want the exit lane to be shorter. However, it did seem like many crashes were at night, which wouldn’t have this problem. Maybe there are just edge cases either way, and the near immediate stop light creates an situation that can’t be mitigated.
