Had the Model S 85D for the past year, happy anniversary, and got 8.0 installed on Saturday. Took it out on a 300 mile trip to 6 separate supercharges and not one incident. No nags, no HOLD ONTO THE WHEEL warnings. All behaved as expected with a few hillcrests losing sight of the lanes, which I easily regained control over. But let's be ABUNDANTLY clear, there is no HANDS FREE driving. If you are doing it, then you are violating the terms of usage in which case any crash under AP control could be deemed to be your fault, as the agreement clearly states YOU are in control, not the car. Accept it for what is is, not what you think it should be.
Version 8.0 is better than 7.1. There are bugs, but that occurs in every release an I am certain they will be weeded out in the coming weeks. (Usually get an update about once a week, but expect a little more time before 8.0.1 to cover the vast array of bugs and data gathered from the the fleet.) This will only work to improve an already awesome car. I look forward to seeing improvements over the coming weeks and months. Don't really expect 8.1 for a while due to their wish list of adding features previously mentioned.
If the OP doesn't want their Tesla, I am sure there are plenty out there who will take it off their hands.
