I have had very good luck with the FSD beta...BUT...I was just driving back to work from lunch, going straight down a 4 lane road in heavy traffic, and FSD first wanted to turn into oncoming traffic when it left the highway. When I re-engaged it, it drove fine for about a half mile, then SUDDENLY swerved towards oncoming traffic! No earthly idea why it did either of those things. But yeah, I would say that FSD beta is NOT for everyone, yet. You really have to be committed to keeping a CONSTANT eye on what it is doing and be TRULY ready to take over for it at any time! Most people would not want the added headache of doing that...it's not really more convenient than manual driving at the moment. It's more a "really neat thing that the car can do...MOST of the time...that really needs supervision ALL of the time" kinda thing. I enjoy using it because I enjoy watching the progression as it's learning. But most customers would be frustrated with it's failings instead of being happy with the constant improvements.
