You can only hear them at slow speed. Anything above 50kph and the air noise make it impossible to hear. Motorcycles are invisible because a lot people don't take driving seriously and don't check their mirrors/blind spots.
The only time I got into an accident was at a red light. I was stopped in front of a car, which was also stopped. The light went green and the car rear ended me, this was mid day, 100% visibility, my bike was bright red, you can't fix stupid.
