Here's a summary of how it works
Tesla’s FSD v13 uses its multi-camera vision system and neural networks to detect posted speed limit signs (and other regulatory signage).
The detection pipeline combines in-vehicle sign recognition with map-based speed limit data and fleet-derived corrections. Once a sign is detected and validated, the speed limit value is fed into the driving stack to set target speeds (and optionally UI warnings).
There are engineering difficulties (visibility, sign format variation, latency, map vs vision conflicts) which Tesla addresses via improved hardware (camera resolution/fps) and improved networks (v13 architecture).
While not every sign is always recognized perfectly, Tesla’s approach shows an iterative maturation of the capability, especially for v13.

Again, don't get me wrong. I really like Tesla's FSD. It just keeps you on your toes at times.
Mike as you've no doubt seen, there's a ton of construction and development going on especially where you are. "Court"s are nothing new, just like "Walk"s or "Drive"s or "Circle"s or "Crescent"s and so on beyond the usual road, street, avenue.
also, you're near the world equestrian center (esp. on rt 40) where some previously possible traffic turns are no longer allowed because they know how much volume has increased and limit options to lessen accidents.
fsd can only adapt so much to unmapped changes, just like you're having to adapt to all the changes too.
i used fsd downtown ft. lauderdale which had TONS of construction, detours, traffic and cars parked on both sides of narrow roads. that was my first experience with fsd (in a cybertruck no less) and lemme tell ya it was nerve-wracking but it never did anything bad. helped that the car owner was calm and confident about it all.
in this area though i've had great success so far... also had it drive me to an address in the villages which was tricky, but it did great.

excited about getting 14.x... looks like it's starting to roll out beyond influencers now...

Using FSD when behind the wheel is of little interest beyond gadget novelty, but being able to dispatch my vehicle would be of value. Drive to the airport... then dispatch my vehicle back home... then come pick me up upon return. Lots of retail stores have curbside pick up, no need for me to be there. FSD car could drive itself for new tire installation... or follow me while I'm taking a non-FSD vehicle in for service... on and on. In other words, the value of FSD would be more about the vehicle operating when I'm not in it.

I would disagree with you. I used it on a 390 mile trip to SoCal, and it was the most relaxed trip I ever took. My brother in law uses it every day, and although he's in the driver's seat, loves it wouldn't have it any other way. I guess you have to experience it and live with it to understand
Definitely not a gadget in any sense of the word.

Just the concept of it doesn't interest me. I'm sure it works great.
I thought for instance I would always use distronic on the highway, but I only use it on trips. Driving day in and day out I would rather drive it myself.

I think there are some current "inconveniences" that could become modern conveniences with a car that can truly drive itself with no passenger. When I think of paying the $100/month or $8k up front for FSD, I'm not sure I personally receive the value of it from having it drive me somewhere right now. But if my car was doing some of the things that you mentioned - that would be really cool and really valuable to me as a way to maximize my time by avoiding some things I might not necessarily need to do anymore.
Good take IMO!
