I don't understand eating in the car either. Uncomfortable, disgusting, there will be crumbs and bits falling and dripping all over the place over time, turning the car into a filthy pigsty. Which fats will be ok with, because that's how they keep their houses too. You have to stop to eat without risking spilling all over yourself, so you're already stopped, step out of the car and go inside, or sit outside on a bench or even curb. Fuck, sit ON your car, even that's more comfortable for eating. In many places eating in the car is illegal, due to distracted driving laws. I bet it goes hand in hand with eating in bed.
