I DO NOT pull over - EVER
Its simple really. If I am on a road trip, I tend to find it a faster experience altogether if I do not stop, take breaks, etc. Outside of the need for gas, of course. Then, anyone who has elected to join me can do what they need to do in the time it takes for me to fill the tank, wash the windshield and pay.

This obvious has caused some issues in the past. But, its my quirk and I have to live with it :)
