I drive through London often, and I’m surprised at how often the in car speed signs / warnings are inaccurate. Has anyone else noticed this?
That does seem bizarre. i thought the car used both speed sign assist ie cameras across the range as well as sat nav data. Certainly it is pretty accurate in the e class just thrown by the 2018/2020 gov revisions described above. If the speeds are well signposted then the camera should read it. I know the amount of street furniture was out of control when I last lived near London 12yrs ago with far too much signage. I would refer your concerns to your dealer in case it is something to do with the gps not working properly and the cars location not being properly identified.I use the in car sat nav. I assume this is an app. I have driven some roads through London where the sat nav believes I can do 70mph on a 20mph. Seems bizarre!
