Rice is not dirty. It's part of my diet! I need rice at least once a day, or else I don't feel fulfilled.
On a serious note, like Vince said, I will not race when there's traffic. Or if there's a chance of putting someone else's life in danger besides myself and the prey. What I can't stand are people who have total disregard for the safety of other, and zip through parking lots, and crowded streets like they're untouchable.
