I've seen lots of people ask questions about if it's worth getting a black box or not, but not many people have given an in-depth review about their black box. (certainly when I was researching this 18 months ago I didn't find much.) So here is some info about my insurance company.
---------
Insurance company: Marmalade

I've driven about 5000-6000 miles already with a black box, and have thus been able to work out what I am and and not allowed to do. My company gives me a login online and I can view my rides after every journey. I'll list my conclusions:

  • Black box hates it when you slam on the breaks, or break heavily before a 30 zone.
  • Black box hates it when you make sharp turns, i.e always slow down to 10 mph for a 90 degree turn, and never do 40+ on a big roundabout.
  • Black box doesn't really care too much about acceleration. I always floor my car and never get done for acceleration. (unless you have a sports car or a Tesla model S, I think you will be fine)
  • Never been caught speeding in a 30/40, I once did 70+ for 15 sec or so in a 30 and black box didn't register. (do not try at home)
  • If you drive over 80mph for an entire minute you get a small penalty, but it doesn't matter if you drive 80 or 100, you get the same penalty. (I put cruise on 82 normally and don't get any penalties)
  • Short bursts of high speed goes pretty much undetected (30-40 sec at 95mph no prob)
  • Never done 100+ so can't give any info about that.

For me it works like this. Every journey starts at 100%, and you lose a few % for every thing you do wrong.
100-80% - Green
80-55% - Amber
<55% - Red
If you get caught in the red zone, first time it's a warning, second offence is a £250 fine, third offence is £500, £750... The company says that 90%+ of drivers never even get a warning.

The only time I got close to getting fined was when I drove 93mph on cruise on the M4 from junction 1-13 (50 miles), and gave me a score of ~57% (I was the only car driving about, 2AM I don't think it was THAT dangerous). I thought my blackbox was off, because it wasn't registering some journeys before, but magically started working again just for this one

Furthermore, I suggest you look at this chart below. Driving even 90+ can get you disqualified, and driving 100+ can get you disqualified for 56 days, which means you will need to re-take your driving test! Not to mention how this will mess you up with your next insurance quote. Won't be pretty. You can also look on http://www.ukmotorists.com/speeding%20fines2.asp to see how badly previous motorists have been fined for speeding.

tldr; If you want to drive at a reasonable speed (~80mph) and floor it every now and then, a black box is no problem. However if you want to drive ~100+mph most of the time, I think you got other things to worry about. Be prepared to bend over if you get caught.

With Tesco Bank Box here, been with them for 2 and a bit years now never had an issue with my driving style and the black box, only thing they've done is limit my bonus miles (which I don't need). I'm a quick driver for reference

Out of interest is this on Dual Carriageways/Motorways or on any road with a 60mph limit (eg a normal A road)?
