That's a fair point about tax and car maintenance. They don't pay per mile to account for cost of gas at all?
I live in a college town so I feel like there would be a high volume of business in a small area, but I'm not sure if I'd love doing it lol
They do pay per mile (depending on what app you use, Doordash and Postmates factored it in somewhat differently but did add it in), and it does generally outpace the cost of gas. It was just kind of a let down to crunch numbers and watch $100 drop down to $50-60 of real money after delivering for a long shift lol.
Doing it in a college town would probably help a lot. Some college kids tip surprisingly well since they're less frugal when spending their parents' money lol
Other annoying thing for me was that people would often make tons of oddly specific orders with weird substitutions. Had to call a lot of customers to explain things like "sorry sir but Wendy's can't substitute maple syrup for sugar in their Coke" and then I could guarantee I wouldn't be getting a tip.
Pros: when I played Pokemon Go I could find lots of awesome things in restaurant parking lots while waiting for the food. Old ladies were really good tippers.
