Ok I know we shouldn’t be doing things like eating while driving but if you’re going to do it, there’s some good choices to make and some really bad ones. My worst food to eat while driving is the meatball marina sub from Subway. The foot long has about 1 meatball per inch and trying to eat with one hand seems to squish the meatballs in the opposite direction of the bread while biting. With about a 50+ % chance any of those 12 meatballs falling out, it’s pretty much a 99.9 % chance that at least one out of them will fall out, roll down your shirt, pants etc. Other than that any Taco Bell hard taco is also really bad. The soft ones work well. The Sausage McMuffin w/o egg is another great choice as is their $1 breakfast burrito.
Take out Poutine in Quebec is also really messy, not as bad as the meatball sub though.
