The rule is clearly stated in the swedish article that during these drives a person must be present with one hand on the controls just I'm case. Same saftey net, really, remote or not imo makes no difference
Slight difference that makes it all the more interesting: the remote controller watches 10 vehicles at once. I feel this is the same difference as a manned vs unmanned subway, because it means reliability is good enough that you don't need one human per vehicle. Each vehicle is a little bit more autonomous.
Also, the safety net inside the vehicle is clearly just for testing purposes, while the remote safety net is something that can be done in production.
The remote controller can not only watch 10 vehicles at the same time, but also go home at the end of a 6 hours shift and handle the vehicles to another driver without even stopping.
