He has a dashcam, but he can't get it to stick to the windscreen...and anyway he is a technophobe...and yes I can hear you muttering that you don't need much technical knowledge to work one of these, but he has had an Ipad mini for 12 months now and still gets in a tussle with it(even a three year old can use one of those).
It might help his blood pressure, but it would do mine no good at all
