I think we all need to email Ownership Experience. It's not a matter of if but when your car will have wear on the seat posts. Wear started showing on my passenger side only after a few hundred miles.
Not necessarily true. Each car is different. I learned how to enter and exit my Roadster differently than all other cars. I get into a LandCruiser differently than I do my Model S. And I happened to be aware of this issue from the forum before I even got my car, so it was no trouble at all to immediately teach myself a non-rubbing way to get into the car: right foot in, left hand on wheel, swing body into seat without rubbing on the B pillar, lean back. Easy as pie... 500 miles and zero wear.
It's a real design issue for Tesla, of course, and they should fix that for the future as well as figure out how to make it better for current customers. I certainly agree that this part of the design could have been better. It's just not true that everyone will have wear issues. Some drivers won't have them at all, and some drivers will adapt.
"Some" could be a small number or it could be the huge majority, and that's the biggest question... what percentage of people will have this problem? Some, but not all.
