Feels difficult to believe. He reduced speed by 60kmh by opening a door “slightly”? Why did the cruise control not compensate for it? Both brake systems failed

Feels difficult to believe. He reduced speed by 60kmh by opening a door “slightly”? Why did the cruise control not compensate for it? Both brake systems failed at the same time? In addition, the automatic gearbox was somehow stuck in D? Sorry, but I’m sure it’s either human error or a publicity stunt Edit: I didn’t know the C class has any remote control capabilities. Does anyone know more?
