Gas pedal floor indent from fat *** foot!?

3rd car this has happened to. I ve had the car for 6 months. I don t feel like I m putting a lot of pressure on the floor with my heel, but somehow- there is a perfect heel shaped inset in the floor where my heel rests by the gas pedal. I ve never seen anyone else s car with that. I m about 240lbs, 6 2" tall. Assuming my right leg weighs maybe 70lbs...what kind of steel do they use for the floor in these cars. Nissan Sentra, Chevy Cruze, Ford Taurus. Heel indent is through the carpeting, and pressed into the metal. Anyone else have this issue??
