My daughters got a black box. She’s not passed her test yet so only drives locally for about 30 minutes. I’ve driven her car over to Manchester from Sheffield a couple of times. Because she’s in the car with me you have to change the driver over to say she’s a passenger. On one occasion she forgot to change it because we were going away for the weekend. She remembered the next day and changed it. However a week later they have cancelled the insurance. Would not listen to any explanation. It’s a shame that your app doesn’t allow the driver to be changed before the drive rather than after. Because I believe you should not record any of the named drivers driving because it’s the driver that took the insurance out that you are watching not anyone else. Poorest customer service that I have had the pleasure of dealing with. Stay well clear.
