when i ride a motorcycle, i rarely use turn sign ... i literally use my head to turn i don't even use the mirrors because turning my head eliminates blind spots car and bike riders here understand (and accustomed to) what it means when an object in front of them slows down while its rider's helmet turn to left/right but of course it's not safe :( so maybe a better solution is a bike with accelerometer built in (like in iPhone) so the sign flashes whenever i tilt my bike accordingly
