Maybe it uses both? My Honda can tell me the speed limit, and I'm sure it's not using the internet to do it.

There's no reason it couldn't have them stored locally. If your car has an on-screen map, it's probably been downloaded to the car directly like standalone GPS units popular years ago.

  It doesn't. And the sign seems to pop up after I pass a speed limit sign. EDIT: Here's info on it. https://www.dowhonda.com/2017/11/17/traffic-sign-recognition-system/ https://www.dowhonda.com/2017/11/17/traffic-sign-recognition...

  Well, the problem with builtin GPS in cars is that you will often find yourself driving on brand new highways, while the car is complaining that you are driving in terrain and need to get back on the road.

  >> I'm sure it's not using the internet to do it. > How sure are you? Pretty sure. The Honda Sensing display of the local speed limit changes on the dashboard at the instant you pass the sign, it's too exact to be using GPS. Nobody has geocoded the location of every sign in America, that would be too much work. Also, it's often wrong but in ways that you would be wrong if you were just reading the signs. For example, it will switch to 55 MPH speed limit in a 70 MPH zone on the interstate after it sees a sign that is intended for trucks only.

    My garmin does this instant speed change, and it is pulling GPS.

      Does your Garmin also refuse to say anything until you pass the first sign, and also stop indicating the speed limit if it's been a long time since you saw one, and also from time to time pick up spurious roadside signals as speed limits, indicating 70-100 MPH in 25 MPH zones, and also finally does your Garmin stop indicating speed limits if you cover its forward-facing camera with a piece of tape? I think the clearest indication that Honda Sensing does not use location data for speed limits is that Honda Sensing is available on cars that don't have GPS at all.
