Will fitting a dashcam to an EV reduce the range?
We've recently bought a Toyota Bz4x electric car and I'm wondering how much effect on the range running a dash cam will have?

Your dashcam and any other electrical systems plugged into your vehicle are powered by the 12V battery, while the drive motors take energy from the main battery, so using a dashcam does not directly reduce the range of the vehicle. The 12V battery can draw power from the drive battery when required, but a typical dashcam uses around 300mAh of current, which is several hundred times less than the power required to operate the air conditioning.
