Seems pretty irresponsible considering they're death machines. I had one in my blind spot on the highway the other day, and it was virtually invisible. I always manually check beside me too, I never trust my side mirrors. Literally couldn't see her. Luckily, nothing happened, but I don't understand what people are expected to do when they can't see you.

A quick web search indicates that in 2016 motorcyclists were 28 times more likely (per mile driven) to die in an accident than those driving a car.
