They won't even process a reimbursement for driving over 250 miles. It would OK if it were just a cap of 250, as many people can drive for well below the IRS rate, so it might still make more sense to take their own car.
We do per diem, too, which works out well for me because part of my travel expenses are the petsitters, which I probably couldn't get reimbursed on receipts, but since the per diems are reasonably generous I don't end up taking a loss.
Yeah, it gives a lot more flexibility, and you don't feel like you have to keep track of everything. You just spend whatever you want to, and keep the per diem.
