When I was with Northrop-Grumman IT we switched to Runzheimer. The only way you could stay ahead of it was to NOT drive anywhere.
Your mileage rate changed every month and fluctuated with the cost of gasoline in the area, at the end of last year I was making around 18-19 cents/mile with a fixed rate of $420 or thereabouts. Compare that to the 45 cents/mile we WERE getting prior to Runzheimer and you'll see it's a terrible service.
