I think for even the shortest delivery of a place 10 minutes away with a 2 mile distance is supposed to tip at least $5. and if the delivery is done in 30 minutes, that’s an effective wage of $15/hour, that is, if they get orders back-to-back.

Since these shitty companies don't provide vehicles or gas money most of that $15 is going to vehicle costs.

When I delivered for a pizza place in the late 90s in a midwest college town with my own car I got 15-20 per hour between base pay, gas and car use subsidy, and tips. That business was 90% deliveries, so the delivery was baked into the cost.
