Grade separated metro public transit is often likened to a horizontal elevator, you step in through some doors, doors close, stuff happens, doors open, you step back out later and you're somewhere else. A taxi is never going to be quite like that because the acceleration profile is too different and because you have to explicitly summon the taxi, it doesn't just turn up periodically like an elevator or metro. Also: The paternoster isn't actually dangerous. It just looks scary and it's not as accessible because it won't wait.

I like this analogy. > it doesn't just turn up periodically like an elevator Aren't elevators summoned by a button and then have their destination set by different button? That seems very similar to tapping in an app to "come get me" and tapping again to "take me there".

  It depends. In some tall shared buildings (the sort of place a company might rent a single floor because owning a building is eye-wateringly expensive and unnecessary) the elevators are intelligent and hooked to gate ID, so, if somebody arrives at the gate with an ID for floor 12, the next available elevator picks floor 12 and opens its doors. After all you're not allowed on the other floors so it's pretty obvious where you're going.
