Right Turn On Red

Why do people make right turns on red lights in the face of signs that say "No Right Turn on Red"? This has always intrigued me.

Legally, there is no difference between, on the one hand, passing a red light to go straight or make a left turn and, on the other, making a right where the sign says "No turn on Red". If you are caught, you will get a ticket whether you make a right turn or a left.

Yet, you don't routinely see people passing red lights except to make rights.

I've also noticed that it's overwhelmingly men who do this.

Obviously, it's easier to make a right on a red rather than a left. Drivers probably also think it's safer (but the sight lines are usually bad which is why the sign prohibitting a right turn is there in the first place).

Still, I don't really get it.
