We ordered our Model S after a 24 hr test drive and I forgot to ask this question to our "salesman". With the programmable mirror memory and the auto tilt in reverse, is the amount it tilts programable too? I noticed when I set my mirrors how I liked them once they tilted they were of no use to me. In other words can you program both the normal position and the tilt position or is the tilt position just a fixed amount of tilt of the normal position? Thanks
