I must be the only one who is all up on the wheel. My back never touches the seat I'm 5'2, so even with the seat adjusted, my little legs struggle to reach the gas pedal and brakes in my PT Cruiser. Oh well...either way, it's a good idea.
JK I carry a scarf in my purse to avoid headrubbing in ANY situation. I also have a "car scarf" just for the car..I wear it to work and take it off before going into the office and put it on immediately when I leave. It's kind of automatic for me now.
