I love my new (Aug 2023 build) Model S LR. Lots of improvements over my 2016 90D which I enjoyed over 7 years and 96,000 miles. With excitement and optimism I have been trying the latest version of FSD. What is the best description? Is FSD like a New Student Driver? Or more like a Timid Old Lady? 1) The following distance is absurdly long. This annoys drivers behind me. And invites others, one after another, to cut in front of me. This even after setting the option to most aggressive. 2) Lane changes, about half of them, are non-sensical. Either unhelpful or just plain wrong. 3) Intersections are a challenge. Hesitant and slow. And sometimes wrong. Yesterday it just froze up, half way through the intersection, unable to decide where to go. This leads to a question: When/where would FSD be better than just doing it myself? The answer is: 1) Interstate-type highways if not too much traffic. 2) Stop-and-go (or crawling) heavy traffic. In both of these cases, Basic Autopilot will do this perfectly. I am hopeful and optimistic that Tesla will eventually develop a useful FSD system. But it's not there yet.
