If you own a car, you will be more than aware that one of the most expensive things about it is when your insurance is up for renewal. Some people seem to spend very little, while others regularly spend hundreds of pounds per year. Obviously one of the best things to do is not crash, because that can increase the amount that you would have to spend, but what else can you do to help? I have recently had a black box installed that can see how I drive, and how fast I go. It has reduced my insurance greatly because it can now see that I never speed, and that I rarely drive at night, which brings the cost down a lot. Has anyone here tried one of these boxes?
