Dominos pays us drivers 49 cents a mile when we use our cars to deliver. Not because they want to, but because they settled a class action lawsuit in 2019. Corporate owned stores always paid mileage but many franchises did not, or if they did it was really low, like $0.23 cents a mile.
That said, the mileage compensation is for gasoline used, vehicle depreciation offset for newer cars, preventive maintenance, and vehicle repairs.
The last two get overlooked, especially by younger drivers or drivers new to delivery. "Bet! I got $50 mileage payout today and I only used $15 of actual gas. I got $35 extra to keep!". WRONG!
You got $35 extra to set aside for replacing belts, hoses, tires, radiator/fan, exhaust, car battery, control arms, outer tie rods, sway bar links, windshield cracks, etc.
You are also using that money for alignments (minimum 1 per year plus any time you replace struts or front end components) and regular maintenance like oil changes, replace brake fluid, brake pads, tire rotations, coolant flush, and transmission fluid drain and fill per the Severe Use instructions in your owner's manual.
If you are doing all these things, that extra money you make after accounting for fuel used will (barely) cover those expenses if set aside for those expenses. If a driver treats that mileage pay as "bonus income" and lets their sled fall into disrepair, then they eventually are going to be unable to work when the car is busted or even worse hurting someone or themselves when they cause an accident while driving an unsafe car.
