Sorry for your friend. But actually nowadays the car is designed with several these functions which could potentially prevent the occasion like this:
1. deep press the brake to activate the Autohold, for VW cars you may need to activate in the center console area. This could naturally self brake your car and when you press the gas pedal it will run for good without deactivation of autohold needed.
2. Always remember to use the hand brake/E-parking brake to hold the car when needed
3. For the automatic transmission/dual clutch these gearboxes, switch to P when standstill needed, then there will be a mechanical design which will lock your gear as well as your car.
The good thing is in the automotive industry we deliver the technology to make the driving more joyful and convenient, whilst the mechnical watch industry are more about design, heritage, mechanism a bit, but durability I believe is not the most urgent and important factor...
