So you have both hands on the wheel at all times when you are driving? When you can, and you think it unsafe otherwise?
I find that amusing, I drive with one hand most of the time, and use both when they are needed, I watch the road and the people around me like a hawk, that is the only way to stay safe when driving.
I am not trying to pick on ya, but I just have this image of a flustered sweating pale man, both hands clamped to the wheel with white knuckles, at th edge of panic when he has to reach for the radio button swearing at all the people on cells!
