I am not sure how this is suppose to work, or what is happening here. I have a Model S 90D, with HW2 and running the 8.0 software. My car passes many speed limit signs and never records them, however seemingly randomly a speed limit sign will pop up on the display, sometimes correct and sometimes not. I believe it is pulling the displayed speed limit signs out of a database on Tesla servers, based on previous Teslas seeing the signs. Here is why I think this: On a recent trip from Daytona to West Palm Beach on I95, I went through a section of road under construction that was clearly posted as 60mph. The Tesla display continued to show 70mph. The construction was 13 miles long, plenty of 60mph signs along the way, apparently never read any of them. But ... shortly after I cleared the construction area, and the speed limit went back up to 70mph, the Tesla displayed a 60mph sign and alerted me I was now going too fast. That section of road was clearly marked as 70mph, however were likely 60mph a few weeks back when that section was under construction. It appears the display is pulling old data off the server as a default since the camera is not reading it (?) So my question: is my Tesla not reading signs because there is a problem with the camera somewhere, or is this software not doing it at the moment? The demo I had on a model S, supposedly with the same hardware and software, did read signs during the demo. Thanks for help.
