Exercise while driving?

Synamin

I drive a lot because of my work, usually four to six hours a day. Imagine driving half an hour, out of the car 45 minutes for semi sedentary stuff, then back in the car for half an hour or so. Does anyone know of any safe ways to toss in some exercise while stuck in traffic jams? I hate that all this time is going to waste (and waist.)

I do kegels, butt crunches (basically tighten the muscles for 5 sec at a time), ab crunches ( tighten abs bend toward steering wheel)
