Not exactly the same thing but in Formula 1 the F.I.A. mandated a similar system to stop wheels coming off the cars in a crash. This system uses three separate Zylon tethers each bonded to a different part of the car to provide redundancy if one of those parts fails in a crash.
Despite each tether being designed to take 10x the weight of a car, they still fail fairly often in high speed crashes.
