I drive a manual car, and as such my hands are almost NEVER both on my steering wheel. Should my GPS still be disabled when there is a passenger in the car? How is it supposed to know that there is a passenger in the car since I now don't have both hands on the steering wheel?
And don't tell me that my stick shift is part of the problem. I am more attentive to the road for one particular reason, I can't just have the car take care of shifting for me, I have to be involved in what my car is doing, how fast I am going, what the RPM's are of my engine so I don't blow it up, because of that I need to pay attention to the road, I need to watch other cars to know to slow down, when I can shift into a higher gear, when I need to down shift, I need to watch the road for any inclination so I can appropriately shift into the various different gears.
Because of driving a stick shift I would say I am better prepared to multi tasking within my car and still operating it safely more so than others.
