When more electric bikes are on the road, it will be interesting to see if accidents increase, because motorists will not be aware of a motorcycle around them.
Motorcycles can easily get in a driver's blind spot, even when they are riding safely.
Headlight modulators are an excellent safety feature. I cannot name the number of times I have approached an intersection and seen a driver about to pull out into my path and then stop and do a double-take at my flashing headlight.
