Exactly. I ride like I'm invisible and use hand signals along with turn signals. A few years ago I added LED DRLs (daytime running lights) and upgraded the headlamp and pass lamps with halogen bulbs. I've had fewer incidents of cars pulling out in front of me since then. The DRLs will put your eyes out if you look directly at them. I have an RTB (run-turn-brake) controller that keeps the rear turn signals on for running lights and flashes the signals and brake light three times when stopping.
I always leave a couple of car lengths in front of me for an out at stoplights, leave it in gear, and keep an eye on the mirrors for cars. If I see a car coming up I'll pull the brake a couple of times to get their attention. I've seen riders not paying attention at stoplights - stop right on the stop stripe, in neutral, while looking at a cell phone. Geez...
I've had a couple of close ones from drivers not paying attention. My only accident was in my early 20s giving a Yamaha 360 Enduro a little too much gas while the front wheel was in the air. Skinned up a little and a few days in the hospital from jarring something loose in my insides. I landed flat on my belly then rolled. Did you know a t-shirt doesn't offer much protection?
