The only exception is the US, and even then that doesn’t apply in Manhattan.
Public transport can be faster for going from A to B, but most people live a couple of kms from A and they're not going to exactly B but somewhere in the vicinity. The "last mile" will more likely be by robotaxi.
Lower prices don't make things more convenient or fast.
> You're shopping? Just put it in the trunk. Have fun with 4 grocery bags on public transport.
Here is "The Shops at South Town" mall in Salt Lake City: https://www.google.com/maps/@40.5617162,-111.8944801,171m/da...
Note that some parts of that car park are 300m from some of the shops in that building. (There are choices of shops and parking spaces larger than that, but it looks like I can easily justify 300m without resorting to maxima).
Here is my old apartment: https://www.google.com/maps/place/Prenzlauer+Promenade+1,+13...
Note that within 300m of that address — i.e. the bounds of the example American shopping mall car park — there are 6 [super]markets, a pharmacy, at least five cafe/bakeries, two cinemas, several takeaways, at least two restaurants, a dentist, a car repair shop, a car dealership, a pet-goods shop, a kitchenware shop, a newsagent/post office, two sets of tram stops, four sets of bus stops, and I'm not counting any corner shops ("Späti" in the local language).
Carrying a few bags of groceries around inside well-planned cities is pretty trivial. Anything connected to that area by a single mode of transport is no harder to take shopping through than the transit systems within a mall — escalator, elevator, travelator — and that means one of the main commercial areas of the city (Alexanderplatz) and the road to it (which itself is basically a 3km long half-density strip mall with a tram the whole length and a railway crossing it in the middle and another at the south end) are both trivial to reach even with shopping — I've even seen someone taking an actual, literal, kitchen sink on one of Berlin's trams.
Even in my current place, still in Berlin but close to the outskirts without the advantages of density, a mere four grocery bags is easier to get through public transport than it is from one end of an American car park to the other.
You are replying to a straw man, I never said anything like that. It makes for dull discussions.

It's unclear to me why you compare it to a geographically unrelated area. You should compare the public transport with a robotaxi alternative. At similar pricing, how is convenience and speed impacted.
Your public transport with robo taxis takes up far more space in the surface than there is available in a normal city, as shown in this photo.
