my new (to me) car suddenly started looking raggedy because of the crumbs that had accumulated.

Many years ago a friend of mine stopped eating in the car as a way of reducing fast food consumption. Worked like a charm apparently.

Also the dog was snacking in the car leading to crazy drool stains.

To top it off I’m prone to spilling on myself even when I’m not eating in the car – clearly this kind of thing is exacerbated when I’m eating at 60 mph.
