Now, 'black box' that alerts when car's about to break down
London: A Black Box that warns of faults in a car before it breaks down is to be launched by the RAC motoring organisation.
The matchbox-sized device slots into the vehicle's computer system and transmits data before and after a journey, the Daily Express reported.
If the car breaks down or has an accident then it will automatically alert a patrolman with its location and the nature of the problem.
The device updates computers at RAC headquarters with information about how the car is running. If a fault is detected, drivers receive a phone call, text or email.
The black box also detects engine and gearbox problems, checks batteries, alternators, brake wear, throttles and filters.
All 1,700 RAC patrol cars have the device and will be available to all RAC members this year with the cost added to subscriptions.
