+ The fact that you are able to receive cash rewards for driving well is a great incentive for any young driver. - 'Usage' is very inconsistent and continuously changes day by day even though the majority of the time I am driving at the same time and the same route too. I also think that it is unfair to be marked down due to the time at which you drive because sometimes you cannot help driving later on in the evening. - 'Smoothness' is also very inconsistent - despite driving well and carefully this is continuously changing and I am unsure to why. ~ In the future I would perhaps like more detail into the reasons of my scoring, such as: harsh braking/acceleration, fast cornering etc. But overall I have been very pleased with the black box - no brainer to use Carrot as your young driver insurance company because not only do you save money, you can also earn money back.
