Here in the UK, not sure if it occurs elsewhere too, insurers are forcing people to install black boxes that monitor their driving. For some they even impose curfews and tiny mileage limits. It’s expected they’ll become required to even be insured in the near future.

Now since these things usually connect to the car’s OBD port and monitor what the car’s ECU receives, could they be fooled? Theoretically you could connect a mock ECU to the device that feeds it fake signals, does anyone know if someone already managed this?
