This sounds more like an expense of your business that they refuse to pay you for. You should get the person receiving income for your mileage to pay for this and not the government. You are asking the same thing as the person with 6 children. For the government (Taxpayers) to subsidize your personal choice. You can move to a different job that does not require your to spend personal money on the job, just like they can control how many kids they have. Your job has received this subsidies in effect since they have not paid you for the mileage.
