Yes, I watch behind me as well. But that's the direction stuff sneaks up on you anyway. Some places I stay in gear. Other places I do not. It's a feeling developed over years. I've been hit from behind twice by cars and once by motorcycle. A couple of years ago at a stop light, I saw a car from behind that wasn't apparently stopping, and I slipped up along side the car in front of me, in the gutter. That car panic stopped close to the one I got friendly with. Tailgaters, same as when in a car. Slow down, and open the gap in front of you. You're stopping for two. Let them pass. Pull off and stop if you have to. edit: I'll be adding lights to my city bike soon. Mostly small LED stuff on all sides. Switched, but available to use. Big wiring job.
