Speaking of pockets, that's usually where I put my Hot Pocket. If I leave my car in the hot sun for a couple hours then my Pocket goes from frozen to lukewarm.
Fueling our cars with tacos would indeed be a lot cheaper than gasoline, but unfortunately the emissions from low Taco-Bell-grade fuel would accelerate global warming
Counterpoint: is it better to put the TB-grade taco into the car than into a human body? Nvm, that seems to get into a whole "exactly what type of emissions are we talking about here?" side-track:-).
