Why is it that rental car companies get away with so much? There are many scams running, and even in Europe where consumer protection is supposedly stronger one can read about all money they make off unsuspecting consumers (if you don't trust the reviews online you can see them on the flyertalk subforum, including those from long-term FTers).

It used to be many industries weren't well regulated. Now airlines are pretty well regulated, hotels as well, but rental car companies?
