Cybertruck on full self-driving (FSD) 12.5.5.3 drives us through fog, ZERO safety interventions!

Crissa - Could you please explain why the poor reading of signs is related to bad patents as opposed to bad hardware/programming? My CT still wants to go 55 in our local school zone (which has multiple physical 15 mph signs). ??

It can only match signs it recognizes, otherwise it uses map data and lane width clues.

It cannot apply optical character recognition to signs as that 'concept' is patented. There's several approaches that are patented in different ways.

And the roads in Oregon and California are just better mapped.

Yes, Chuck Cook just also confirmed this morning that if FSD sees a speed limit sign, it will use that speed limit, otherwise it uses map data -



From my experience, on versions 12.5.* it recognizes speed limit signs 90% of the time.

thanks. I assumed map data would understand that there’s a huge school there and it’s a school zone. I guess not .

That's what HD maps are for, but they miss important data like that.

Until we can get rid of the insane process patents against the car reading signs directly.

Yeah, they have a collection of sign images that it's trying to match, but it's less good than direct OCR as if there is text on the sign (like for truck limits or times or school zones) it'll screw up much more often.

In about two years these patents should expire.
