While it is very reassuring that the car is able, the speedpoint chosen by Tesla – 50kmph — is not. I'd rather a car not be remote-controllable at anything more than a slow crawl, and 50kmph is quite capable of making such a heavy car dangerous.
I'm not sure what are the exact conditions for the Tesla OS to be overridden by other internal systems, 50 km/h was just a placeholder value for "lower speeds".
