Why not just raise the fixed rate reimbursement schedule?
Because any fixed rate schedule would be incorrect as soon as it was published. Fuel rates rise quickly, and fuel prices vary widely through the country. If the fixed rates are based on average prices, by definition, some prices will be higher, and some lower. It is inherently impossible for any fixed rate plan, based on averages, to be accurate for everyone. Someone will end up being reimbursed for less than they actually spent, and some people will get more than they actually spent. While those who get more will probably not complain, their overage should be used to reimburse those who had a shortfall. Accurate reimbursement for all is the goal.
