I think cities like Paris or Tokyo that are transit leaders in the world should experiment with new technologies especially on the urban fringes like this. There is certainly plenty of room for innovation especially if the cost is low. If it doesn't work out, then it can be replaced in the future.

My problem is with US cities that want to use gadgetbahns like Boring Company on major regional corridors even when metro, tram, RER-type systems are a better choice.
