    My car doesn’t have a reliable km/h gauge so I used an app to poll the speed of the car and show it up on my phone exactly in the way you described.

          A device talking to satellites in space is less exciting than some wire going to the engine 🤔

            Gps is a standard, anyone can do it. ODB2 is a mishmash of vendor spesific magic dust, and trap doors. It is impressive if you find a device that handles any car.

              The basic ODB2 stuff – which includes the speed readout – is a standard mandated by the government. It’s stuff like being able to talk to other modules over CANBUS that’s manufacturer-specific.
