Do you seriously think that the main challenge Tesla is going to face when trying to scale Robotaxi up is that there isn't enough room on the roads for all the Teslas? In a world where there's currently a dozen Robotaxi Teslas per city?
If you consider that "the world" is "the US". But in countries that did not completely fail their urban planning, public transportation works. Now admittedly the US probably has to compromise because of how it was built.
No way the robotaxi works e.g. in Europe. And that's without considering the fact that robotaxis belong to a guy who makes nazi salutes.
The US is a modern country and was built in grids, incredibly easy to build any kind of transportation network on top of.
In Europe, large portions of cities and road networks were built before any kind of engine was even invented, and so it is incredibly difficult to retrofit onto winding lanes and tiny cobbled city streets.
In cities in Europe, you can actually walk. Many times you're faster by bike than by car. And public transportation works well (plus you can put your bike in the bus/tram/train if necessary).
> it is incredibly difficult to retrofit onto winding lanes and tiny cobbled city streets.
Agreed. But on top of making them more beautiful, the fact that it's harder to have 6 lanes full of cars is desirable to me.
