It can yes. The point is , you cannot legislate away accidents and death. We hear about how safe air travel is because we have perfect data.
How many miles of successful accident free motorcycle travel happens around the world in a year ? We don't know. But it's obviously a hell of a lot.
But since we don't know the data , we can't make a comparison. But oh man air travel is so safe. The only safety feature in an aircraft is the stats. No parachute , no helmet , nothing. "I'll make it" is the only safety feature. But when you use that logic in a motorcycle , you are called an idiot.
Because helmets are cheap enough , we convince ourselves that its crazy not to wear one. But any real safety device on an aircraft is too expensive , so we just gamble.
