The reimbursement requirement is baselined with respect to minimum wage, so it could be effectively $0. If it is not $0, the form would be additional W-2 pay, which is allowed by law, and this would be subject to all taxes. On top of the tax loss, calculation would not be at the generous IRS mileage rate that drivers currently exploit, but true expenses which most say are lower. Yet people continue to think drivers are stupider than they are at doing what they do every day. It's pretty fucking arrogant.
