I thought the black box wasn't bad at all but I drove at night for 20 minutes one day and it made my score go right down to 35 out of 100 for driving at night. It has now been 3 weeks since and the score is at 85 and I haven't drove at night since. This is unfair as the score should have gone back up to 100 weeks ago. It says avoid driving at night regularly but I have only done this once. This is wrong as I was picking my dad up. I shouldn't be discriminated because of people driving dangerously at night as they would do that anyway regardless of having a black box or not. Something needs to be done about this ASAP.
