Just finished a weekend venture from the Bay Area to N. Lake Tahoe, in a 75D with .42.
Overall, it handled most situations better than previous releases. No diving into off or on ramps, better handling of confusing lane lines than I expected. One location in Sacramento, involving a left lane transition into the local light rail station, westbound, it handled with surprising aplomb.
I did notice that on tight curves in the Sierras, at >75mph, it struggled. Maybe I shouldn’t drive so fast... I also noticed that it decelerated ahead of these curves somewhat. Not enough. Maybe I shouldn’t drive so fast.
I observed some slowing due to adjacent lane 18 wheelers. But it was the Sierras, and the curves were tight. Maybe I shouldn’t drive so fast.
One noticeable moment - I was in the 2nd to leftmost lane, in my red MS. Next to me, in the leftmost lane, was another red MS. I was on AP2. She was an older MS (old style front fascia). As usual, on a right curve, my MS favored the left lane line. Her car didn’t just favor the inner lane line, she crossed it. I was on it, and overrode the AP2. We would have made contact otherwise. My MS didn’t notice a thing.
Couple of thoughts: 1) My MS should have noticed. 2) She wasn’t on AP. I’ve never seen a Tesla favor the inside lane on a tight curve, especially to the point of crossing it.
One other incident: I was requesting an AP2 lane change, to the leftmost lane. My MS immediately started the maneuver, including adding acceleration. It apparently didn’t notice that the car in front of me was pretty close. If I had allowed it to continue without taking over, I think my MS would have clipped the left rear corner of that car. That was a little spooky.
Bottom line for me. Overall, this release is very good. But it has sufficient limitations that one must stay alert at all times. It is ADAS, not FSD.
