The GA Telematics app in itself is generally well designed (if a little slow here and there). Although what is totally unforgivable is the black box which is shoddy, to put it politely. Be prepared to be told that you were speeding and that you’re accelerating and braking is bad no matter how safely you drive. If you start your car and sit still for 10+ minutes then turn your engine off you will be given a score of 0/100 which is infuriating since they reserve the right to cancel your policy if you have a single journey score of under 50/100. The premise of a black box policy is sound, but in practice the gps it relies on is comically bad, my experience with this company has really put me off of taking out a black box policy in the future.
