AMAC,
Glad to hear you surveyed. Hope there aren't any lasting injuries. We live in an age of distracted drivers, and a lack of education about the awareness and approach to motorcycle and scooter riders on the road. The most we can do is manage the factors that can lead to a crash. Like you said, hone our skills. I like to think that I managed to lessen the injuries on my crash by turning in the opposite direction of the left turning vehicle that came into my lane back in May.
A lot of motorcycle safety sites, writers and authors suggest that braking is the way to approach that situation in order to reduce your speed before you hit a left turning vehicle. I have trouble with that advice because it assumes that you will hit the car, and not the other way around, as in your case. Reducing your speed doesn't help you if the car T-Bones you.
Since a lot of accidents happened because riders don't see us, it does come down to visibility, or getting noticed. I'm not a big believer in the Loud Pipes Save Lives idea. If think it causes more confusion.
Do Scooter and Motorcycle riders need flashing lights or something else?
