When crossing a busy 4-way intersection, get closer to the traffic in front of you and let them run interference for you.

Stay to the right or left in a lane at a stop light to avoid to crap people drip from their cages.

Pay particular attention to the old beaters out there. They give even less of a crap about you.

Always do a safety check before starting out (lights, brakes, chain, tires....)
