Tragic. Especially with a young family. However, it has to be said that he was virtually asking for it by taking zero precautions before going under the car.
Quite a few manufacturers are no longer providing car jacks as standard equipment as they want customersl to rely on those crass puncture-repair kits to get the vehicle to the garage for the replacement tyre. Not discounting the tragedy of this incident but presumably it rather endorses the manufacturer’s position (regrettably).
