Much, much better than version 12 in all aspects. Choosing the correct lane to exit highways - in one spot v12 was never able to exit highway correctly, v13 does it with confidence. Performance on snow covered roads without any road markings is impressive. Slows down before the speed bumps. v12 I would never buy. v13 - I'm now not sure,maybe.

Nearly perfect but I still see an occasional glitch. It tried to veer left at an island to enter the wrong side of the road and I had to intervene. My only disengagement so far but surprised me it would make a major mistake like that on such a simple maneuver that has never caused problems in previous versions. Maybe this version likes to drive on the wrong side of the road on occasion?

In my opinion, this version of FSD feels much more confident and consistent over previous versions. The major plus factor is that the left turn issue is greatly diminished. Much better performance in executing left had turns and staying in the appropriate lane. In the past, I did not trust it to turn left in an intersection but my confidence is building as the turning performance is much improved.

Good- real good on the highway. Two major issues: Still takes to long to get into proper lane before taking a turn; FSD goes asleep sometimes and slows down over time. Need to push the go pedal for it to snap out of it and go the determined set speed. A few minor ones- still has dry wiper issues, doesn't slow sufficiently for raised railroad tracks.

13.2.2 is very smooth. A big improvement. I run in CHILL mode. Standard is a bit too aggressive for these old bones. Did one intervention to report a repeated error on a left turn into a left turn lane - left side of a double yellow line, it would correctly move right but should not have been that far left in the first place. It did a tee turn around in my driveway! Did an end to end garage to parking in a parking lot.

Major improvement from v12. So many great new features, and the ride is much more accurate to the profile. Tesla is really getting close to autonomy. Needs work with leaving garage, parking where there aren't marked spaces. I have a tough UPL coming out of my neighborhood it struggles with and with v13, handled it very well!

Much smoother and more consistent FSD behavior.

Best ever. Nearly perfect.
