I test drove a Cybertruck a couple of months ago. The FSD tried to make a left turn out of the middle lane. So I took over and went straight. To be fair it was a construction zone and lanes may have shifted recently.
It did pretty well on the high way. Not sure about letting traffic merge. The Ford and Subaru are bad about letting in cars merge in.
It did pull out in front of a car on a side street. Not sure if the car was blinking to turn right, but I had to take over.
It did get stuck making a left turn onto a busy street from a side street. I had to take over and do a Right turn then a U turn.
The two biggest things were, I really did not know were I was or how to get back to the dealer, because I did not Navigate to the super charger.
There seems to be a reliance on cameras/screens for visibility. so you end up looking at the screen, but then FSD penalizes you for taking the eyes off the road.
Not sure how you handle these issues if you are a passenger in a self driving taxi.
Several times I found myself talking to the car telling it how that was not going to work
