A car ride at the right time to the right place is also just a lot more valuable than a burger at the right time/place. Need to get to work and can't wait for the bus? Have a plane to catch? It's late and there's no transit running? There's really one way to get you where you need to go, especially if you have multiple people or bags.

But fast food slop? Outside of rare situations, you can find comparable slop (even just at a gas station or 7/11) elsewhere, or you dig deep in the cupboard and have a can of soup or something.
