Agree so much with this video, especially since I am American and have experienced some car-infested cities in my time. I just wish I'd hear the same things from our political and cultural leaders as opposed to a person whose entire job it is to say this kind of thing.
Incidentally, an argument you hear in Cyprus (which has a similar urban planning and car-dependency issues as the US but an extremely smaller scale) is that Cyprus is too small to be designed in an urbanist way.
Now, full disclosure, I kinda agree with that in a very specific way: there's a strategy, when talking about public transport in Cyprus, to pretend like the problem is the specific mode of transport. When Cyprus got buses, people boycotted them because "the bus-stops have no shade, no wifi, and anyway trams would be better". Maybe sensible on the face of it, but then when a tram feasibility study found weak support for tram and the bus infrastructure including the bus stops began tangibly improving, the tune changed: "trams are too slow, we need a subway in the major cities". They keep moving to goal post further and further into unnecessary infrastructure (some going even as fast as saying that Cyprus needs high-speed rail, which is ludicrous) so that they justify keeping the place car-exclusive.
In that specific way, I do agree that a country can be too small for some modes of transport. I don't think Cyprus needs more than buses and a few tram lines. Anything else is excuses to avoid doing anything at all.
Now, the USA is clearly big enough for high-speed rail and it has many cities that can support a subway system.
High-speed metro sounds sensible for Cyprus, it's not like you can't accelerate to 250km/h or such on stopless stretches between the large cities. Do you really want to have less rail than Mallorca.
Why would Cyprus need a high-speed metro, when over-ground light rail and electric buses can offer all the benefits (the distances are tiny) for a fraction of the cost and other regulatory hurdles (one of the biggest ones being the archaeological sites protections law that has enormously delayed countless underground projects before).
Do you really want to have less rail than Mallorca.
I want things that are fit for purpose, even if they are not flashy.
