I recently drove a rented Tesla 3. On a highway in Norway it failed to detect speed limit signs in like 25% of cases. And if the speed limit sign was a temporary one due to road repairs it failed with those like 50% of times.
And this is with stationary objects designed to be seen and easily grasped by humans.
Teslas do not read speed limit signs or basically any signs other than stop signs, including not reading “Do Not Enter” street signs. It is using the wrong speed limit because their maps do not list the correct speed limit.
Signs are nice but the simplest way to know the speed is to store it in a database and look it up from position.
In fact roads should have barcoded position markers everywhere. That way you could navigate without gps and all road signs could become virtual. Just download a road marker update.
That's not really how speed limits work though. People take their cues from road design and conditions, not what the speed limit actually is. Virtually changing speed limits is dangerous because it causes you to think you are altering the behaviour of traffic without actually doing so.

We could put GPS beacons on all pedestrians.
The sarcasm tags are missing.
In Norway you are not getting Tesla FSD.
