I have been for many years being an avid supporter and editor of OSM, in my case “that road” has the right info (in both directions) and .... unfortunately I don’t think it’s a source, if this was so, it would have updated by now (going on a year).

Where does AP get speed limits from? How can I fix/ask to fix them?

There are two roads on my daily commute where the displayed speed limit is wrong -- the township dropped the limit a couple years ago so they could set up speed traps for safety reasons. When I got to OpenStreetMaps, there was no limit set on these roads. I updated it anyway - it'll benefit someone someday at least.

AP1 is MobileEye which most definitely reads speed limit signs.
They are the ones that hold the patent on this, hence why Tesla cannot do it without paying royalties for use of that patent.

From what I've gathered, and experienced myself, OSM is used for parking lots. I've edited OSM for a local lot that didn't have the parking lanes mapped, and after an update my car followed the lane lines on Smart Summon, when it didn't before.
There's a long stretch of road I take directly to the freeway, where both Tesla maps and Google Maps lists it as 35 mph, when in reality it's 40 mph. OSM also had it as 35 mph (it use to be that speed before), but I edited it months ago to 40 mph. So I don't think OSM is used for the streets, at least in my area. I've sent in a correction to Google Maps (still pending). I'll be curious to see if that will correct the Tesla Map when it goes live.

How do you send a speed limit correct to google maps? i see an issue locally where google says 65 and its really 55.

Idea to Defeat Patent:
When a Tesla driver sees a speed limit sign, they hit a button and it takes a snap shot. Then it sends it to Tesla with the GPS info and VIN. Now a land server processes these images with optical character recognition (not patented) to build mapping, They fill in speed limits with it. They give a perk to the VIN #, a "Tesla buck" or a SC kWh. You can't give the same info twice for credit. The Mobileye patent is for in-car processing in real time.
But yeah, it's heavily flawed right now.

This is an extremely annoying issue even for users of basic Autopilot, but I don't see how FSD can get anywhere near deployment without the ability to read speed signs in realtime. The currently used maps have a ridiculous number of errors.
In addition, can someone please explain why sometimes Autopilot will adapt to speed limit changes, and other times not? Do you have to be in NOA for it work? I know you can tap the speed limit sign on the display, and the car will slow or speed up 5mph over the posted limit. Am I missing something? No, I have yet to read the manual, sorry.
In car mapping data for some things is imo very likely sourced from OSM; another instance (no smart summon here yet) A fast road near me, one on which NoA should function fully has it switch on and off every 5-10 miles. When I checked the road in OSM, the points at which NoA switched were the points on the map where the road was broken into segments; some of the segments had NoA enabled, others didn't couldn't see an obvious difference in the road segments so couldn't fix the behaviour to prove it.
Seems our wishes will be met quite soon. Someone tweeted Elon Musk yesterday about this and he replied "Coming soon".

Another not so “cool” Autopilot speed limit feature I’ve seen creep up on 2020.12.11.1 is this:
sometimes while traveling on thruways with NOA on, speed set to 70mph, when passing over an interchange, speed limit in the display will drop to 45mph, and the car stabs the brakes to slow to that speed. This is NOT phantom braking, as there are no shadows or other vehicles around. Plus the speed limit in the display clearly drops to 45. It doesn’t do this all the time, but it seems to do it in the same spot(s) every time. Possibly it’s trying to slow down for the exit ramp, even though the car is not exiting???

TBH I'd be happy knowing how to fix speed limits on the map, but I guess the ability to read is helpful too
I'd like to know too. There's one stretch of road where the in-car speed limit isn't accurate to the real road speed limit.
I checked on OpenStreetMap and the speed limit is recorded correctly there.

One particular strip of road, I had to fix on both OpenStreetMaps (it was blank) and Waze (it was wrong). It's been a few months and it's still wrong in the car.
Does anyone know any other users-can-edit map services? Maybe I'll run through all of them and see if anything sticks.
