My car (not as advanced as a Tesla) reads the speed limit using cameras to parse street signs.
Maps will always lag reality, but this is a commonly driven street, probably not the first Tesla to drive down it-- Waze was using info like this for years, hate to think Tesla is less capable.
In short, there is no excuse for Tesla's maps not knowing about the speed change on this stretch of road.
- qubitcoder 4y agoTeslas most certainly read speed limit signs. They have for years now. My stock Model Y purchased in January 2021 had the feature built-in. With FSD beta, turning off a major highway onto my neighborhood street (very narrow and no lane markings), it defaults to 25 MPH. About 100 feet later, the car sees the 35 MPH sign and speeds up accordingly. In this case, 35 MPH is too fast given the curves, slight hills, and limited visibility. I slow down manually in these cases using the roller wheels. Tesla has gradually improved its speed planning to account for different scenarios. But it's still a work in progress and often requires manual tweaking.
