I guess my bad habits are about the same as most of you guys:

-Sometimes riding in the middle lane (Usually when cars are jammed up at a stop light while also taking up the bike lane)
-No lights or reflectors at night (I bought a cheap light, it broke, i have yet to buy another one. I need to get on that asap though!)
-Drink and Ride. (Not hammered and ride, but a beer or two at the bar and a ride home. Talked to local PD, its legal where i'm from)
-Not always using proper signals when I turn and such / also yielding at stop signs when no traffic is around.
