Exit Playground zone + FSD -> oops

Signage: Speed YY unless otherwise posted.
Triangular playground zone XX sign so on FSD we reduce speed from YY to XX, however the end of the playground zone is noted by the back of the playground zone on the other side of the road as we exit the playground zone. Thus for the next 100 miles FSD can’t be enabled as it feels max speed is XX as that is the last speed sign it recognized and can’t deal with the playground zone ending and speed returning to YY+

As someone else responded to your other post about a hypothetical limitation, we don’t have real FSD yet and AP does’t handle city streets in many cases, nor is it designed to.

This isn't just a hypothetical limitation. I've experienced similar speed restrictions when the car misses a speed limit sign or when it comes across a sign like "end 35 mph zone" and disregards it, restricting Autopilot to 40 MPH on what is actually a 55 MPH undivided rural highway (not a city street). This is common in Michigan due to the way they sign roads, but I've experienced it in several other states, as well.

Yep, common here in WI too.

I agree that the GPS data is sometimes wrong for undivided rural highways and similar roads, and if Autosteer on City Streets (aka FSD City Streets Beta) has those same issues, it will be a problem. Let's see how it works once it becomes more widely available.

IMO, this isn't a GPS issue, as the camera's speed sign recognition takes priority over map info in many of these situations. But yes mapped speed limit data is often wrong, which is now better in many situations (except the ones cited) now that vision has priority. I'm sure it'll get better with time, but it's annoying at the moment.
