The rental car market needs more regulation. I remember car rental companies erroneously calling the police on renters for stealing cars, and billing for "wear and tear." The fuel surcharges and everything else is just a continuation of the same anti-consumer practices.
Car rental agencies are King's when it comes to BS fees and practices.
