I think the biggest problem most motorcyclists have is they don’t drive defensively enough. They ride as if they have a right to the road and, dammit, they are going to exercise that right!
I can’t tell you how many times I have seen motorcyclists ride too close behind a vehicle or suddenly switch lanes without adequately, imo, having checked to see if they can do it safely.
Technically speaking, motorcyclists do have a right to the road, but if they practiced all the common sense safety tips, most of the accidents would be completely avoided.
I do ride a scooter myself, but I always ride defensively. I do not trust other drivers.
