As someone who once had a little more money than was good for him (post divorce so no restraining influence) I bought my Tesla about 12 months ago, it's my primary vehicle and has clocked up about 28k since. The 'auto pilot' is excellent as a driving aid - enhanced cruise control. The manual makes this very clear - but I suspect far too many idiots don't RTFM.
As for the car, lovely to drive and a very comfortable large car for long distances. A little planning is needed occasionally, but frequently doing a Scotland-Midlands-Bristol trip, no big deal. Stupidly expensive, but some mugs have to be earlyish adopters or things don't progress.
