xkcd #2932: Driving PSA

Alt text:
This PSA brought to you by several would-be assassins who tried to wave me in front of speeding cars in the last month and who will have to try harder next time.
Runner up is the assassin that seizes the traffic circle, instigating collisions behind them, just to let someone in out of turn. Only their MO is to delay or prevent a destiny altering meeting of some kind; an advanced tactic.
