BUT!
Last week, I had visitors and they let their Model Y Tesla (2023, I think) do the driving for their entire trip - from driving for many hours to visit me, to driving around all the different sights where I live, and, I'm assuming, driving back home. It was all full self-driving.
I got to sit in the passenger seat a few times. The thing drove beautifully. Parked without an issue, changed lanes, overtook other cars, etc... drove even better than the person at the wheel would have had the feature not been available!
The important part.
