AP is not capable of identifying speed limit signs. At least, modern AP cannot. To identify speed limits, Tesla AP pulls map information, which is often inaccurate outside cities.

Do you own a Tesla?

AP1 vs AP2 vs AP2.5 in the Tesla refers to image processing hardware and software.

The AP1 includes forward looking radar by Bosch, ultrasonic detectors and a forward facing Mobileye EyeQ3 camera at the rear view mirror mount. That camera does many things including rain detection. It also detects speed limit signs.

Well I got mine this summer, I didn't get the full self driving package and my car certainly doesn't see speed limit signs its very obvious they come from map data. It actually makes using AP in town a bit useless because they changed a lot of at the limits but somehow the map data is not up to date.

Apparently identifying speed limit signs is AP1-only, because it relied on Mobileye's technology to do that and Tesla still haven't implemented their own replacement for that feature yet.

It's more of Tesla can't because because MobileEye owns the patent:
