Some I haven't seen mentioned while scanning this list

1. Never leave home without a spare tube and pump

2. Never leave home without a lock. You never know when you might need to stop someplace or pop into a store for something.

3. Always make eye contact with any driver you are counting on to yield (any car approaching you making a left turn and any car in the center turn lane that might turn in front of you).

4. At traffic light corners with a dedicated right turn lane I generally scoot over one lane over to the left and stop right up on the cross walk so that cars approaching from behind can get past you to make a right turn.

5. When making left turns at huge crazy intersections with lots of lanes and especially left turn lights I sometimes ride at pedestrian pace in the crosswalks with the walk signal rather than daring a short left turn signal with lots of cars trying to squeeze through. But that's about the only instances that I'll use crosswalks or sidewalks. The other exception being some bridges where the sidewalk is the only safe place to be.
