You are not thinking far enough: There will no longer be individual (or rather: manual) traffic in the city. The transport modules will all be autonomous and connected, controlled on their own tracks where possible, so that traffic lights are basically unnecessary (pedestrians and cyclists move on their own tracks/paths). Parking spaces are no longer needed because the modules are basically always in motion. This alone greatly increases capacity. The modules are much more adapted to actual demand; several modules can be coupled into a large module, so there are not dozens of SUVs with one person each, but two-person modules or coupled ones that run en bloc like a assembled bus on a route and then “lose” smaller units along the way, while others join in. There is no option to order a specific module (like in your example from afar), but at most a certain class. For example, to reserve a single module that might dock but does not open its walls and thus no additional passenger is “let in.” Obviously, big steps are necessary for this, and we won’t manage it overnight. It will mean big pains for some, but I don’t see how one can still get to a green branch (pun intended) without major restrictions, and at the same time I see in autonomy the possibility to achieve a high level of comfort that causes as little social damage as possible.
