Tesla's autopilot was so clumsy that I stopped using it and forgot about it years ago. I like the adaptive cruise control though, it is more transparent and decidedly more of a benefit, except for its phantom braking moments. Autopilot's requirement that your hands be on the wheel (and do nothing) is a strain over time, definitely boring, and a terrible interface. I don't understand why people would pay for such an awkward feature. The monthlong demos of Full Self Driving I tried were even more awkward. The need to keep your hands on the wheel required a different but nearly equivalent cognitive load to actual steering, when using it in residential and city traffic. The crucial difference is that "the car was driving me" rather than "I was driving the car". Tesla can't convince everyone that their driver assist technology warrants product status; take away driver autonomy and make them pay for it seems like a failure to me. It won't be a product until you can sit in the back, close your eyes and safely arrive at your destination. Good luck getting to that level of quality with this business model. Tesla should be giving the tech away to its car owners and collecting as much data as they can, right? I have points to spare for the astroturf Muskovites to downvote my honest (but embarrassed) customer perspective.
