What does a 1-driver taxi compared to a 2-drivers taxi offer apart from fewer taxi-driver jobs? They can't inherently shorten journeys or avoid surface disruption, we already have taxi services in most cities. This just removes a human job and that's the progress.

Now what about a 3-drivers taxi?

The answer is always the same, people hope to lower the driver cost, which I believe is significant for a 1-driver taxi.

Well, some long-haul coaches have two drivers to allow them to switch-out for safety but keep the passengers and bus moving. Of all the things to get excited about, I don't understand why reducing the labor costs for corporates is one. Improving transportation instead would benefit us all, for example with better road design and mixed/integrated transport systems.
