one of the lads in the office has a black box fitted for insurance, as he says you just chill it bit more it’s saving you cash.
Except in a lot of cases, mine included, insurance premiums are actually higher for a black box policy than without, £670 vs £440 for me, the £670 went up when I declared the modifications on my car, the £440 included them.
I disagree with speed limiters but for personal reasons only, do agree that as speed is a factor in about a quarter of road fatalities in the UK it ‘may’ reduce the number of fatalities.
