As a driver, THANK YOU! This is the #1 problem with bicyclists, predictability. I drive in DC and I have literally NO IDEA what the hell a bicyclist is going to do -- which makes them little road terrorists to me.

I have watched a rented bike (in DC) ride from pedestrian walkway -- onto street (along side) -- into middle of road, then slow down and ride through a red light -- then stop at the next red light. This was inside of 2 minutes. Very scary from a driver perspective.
