A number of years ago I hurt my right shoulder through a bunch of things like playing softball and hang gliding. The net of it was that I had to get it scoped, and they took out a bunch of loose bits. I even have a videotape of the inside of my shoulder. After the surgery, it felt much better than it did before, but it still always hurt a little. Skip forward a few years and my new Roadster arrived. I was really excited to drive the car, but it takes considerable force to turn the wheel at low speed. This just *killed* my shoulder. I was trying to turn only left handed and whatnot, but after having the car for a couple of days I was wondering whether I would have to sell it. However, I decided to stick it out another week and it stopped bothering me. Not only didn't it hurt to drive, it didn't hurt at all. Ever. The Roadster was physical therapy! This was confirmed a few years later when I had it in the shop for some body work (I hit a raccoon) and it took months to get it back. My shoulder started hurting again, then stopped when the car returned. I still haven't figured out how to charge my medical insurance for it, but I'll be sure to tell the forum when I do.
