I rented one for a few weeks in late 2021, and the experience completely turned me off of Tesla's FSD.

During a 2 hour drive on an interstate on a clear, sunny day, FSD started steering into another vehicle 3 different times. One was a truck, and another was a wide load house being transported. I'll admit that is an odd case, but "don't accelerate straight into a house that is at windshield level" seems like a pretty simple ask. It did this multiple times and I had to temporarily disable the cruise control.

It also failed miserably on curving state highways, to the point that I turned it off after about 20 minutes.
