TL;DR: My black box is falsely accusing me of speeding, leading to my policy being cancelled. If you have any experience of this, please let me know! Flowery Version: I had one of those telematic boxes on my car for insurance, through a company which shall remain nameless, but is large and reputable. All was going well, beautifully low prices, driving scores hovering in the 80-96/100 range, lovely! Last week I had a holiday to Scotland (It was lovely thanks, all sorts of weather, walking, climbing, and relaxing etc ) and when I got back, I thought to myself 'Ah! I shall check my score online, see what it thought of my motorway journey'. On I logged, and was flabbergasted that my score had dropped into the 60's! I looked closer, and saw that I had been flagged for 'extreme speeding', going 101mph on the M6. Now I thought this was odd, although occasionally overtaking slow traffic, I doubt if I strayed over 80mph which is the boxes 15% allowance. The next day I phoned the helpline, and spoke to a charming young lady who assured me that 'As you didn't get an email straight away it's a computer glitch', and that it had been noted as such. Today, 2 days after that phone call, I had an email saying they would be cancelling my policy. I phoned again, and spoke to a man who just kept repeating that it was 'meticulously checked by a team of experts' and there was nothing he could do! Has anyone here had problems with a black box, and how did you sort it? Thanks all! I drive a 1L Skoda citigo, the top speed of which is roughly 107mph (I have read, not tested!). I had a passenger, and luggage, so I'm sceptical it would reach that sort of speed without me noticing.
