I would give the black box less than one star if I could. Its a ridiculous system that brings down your score dramatically even if you break harshly once. After I had realised this was the case, I monitored my acceleration, braking & speed scores and it still wasn't enough. They say they care about safety BUT due to the worry from increasing my score I spent more time looking at my speedometer than the actual ROAD. Its not worth it at all. Pay that little bit extra for NO black box, you'll be a better driver without it. My insurance quote was £1190 for the first year and with a GOOD drivers score (bearing in mind i hadn't driven my car between December and march 2021 as it needed repairs), so the driver score was at 100%, my insurance renewal was £1160. What a joke. Would not go with rac again, scammers.
