Well I finally got into the beta program with the latest build and that STILL didn't fix it ... at first. After a couple of days, I turned it on and then I went over and adjusted my wheels and mirrors. The next time I drove, it was on and has been ever since. I have no idea if that was a coincidence or actually what fixed it. I tried changing a few values on the same screen as this feature, but that never worked. When I went over to the Pedals and Steering page and adjusted my wheel and mirrors is when it saved.
Like I said, no idea if there is any correlation whatsoever. I was beyond frustrated with it. So happy it finally stuck and I love this feature. Give it a shot and let us know.
