I bought my Model S in March. It was the promise of autopilot that put me over the top. I really like TACC, but there is still lots of room for improvement. For one, it does not adjust the speed down for curves, which can be pretty scary on surface streets. It also does not stop for red lights or stop signs. I believe the speed adjustment for curves will come with 7.0, but traffic signal awareness will come later. In the long run, they should work on driving styles and optimize range. I often find that on surface streets I can get better energy efficiency driving smoothly than using TACC. I am optimistic this refinement will come in time, but it's important that with every release like this, the cars become a better value. This is what drives demand, the willingness to spend hard earned money on a product.
Soon to obtain a 5 star rating for safety will require assisted driving safety features that tesla is now including in its cars.
This has clear economic value and will improve insurance rates. Maybe .
