Today on my way to work, I pulled in behind a large 4x4 truck at a light. All of a sudden he/she puts the truck in reverse and starts backing up. I was trying to move backwards on my bike while straddling it. was able to mount my bike and ride up on the side walk. I was at first thinking that I should have aligned myself behind him where he could see my in his drivers mirror, but realized that would not have helped today, from all the dew on this side and back windows. He would have never seen me anyways. I assume he was trying to trip the light by moving around.
