New CityNerd video:
Basically, nearly every single problem he pointed out is true of public transit or urban living.
Not going to do a through analysis but at one point he mentions "noise pollution" as a detriment of cars.
So how about public transit?

Are tiny apartments immune to noise?
Another issue he has is with lack of exercise. On this I have two objections. First, if they are advocating for 15 minute cities with near door to door public transit, I have to question how much exercise on gets. Next, if we accept the current model in the US and most countries (except a few areas) then public transit takes LONGER thereby reducing the time to exercise.
In reality, health is more of a factor of personal will than muh transit infrastructure.
Self harm is brought up but one and always throw themselves in front of a train or subway.
He brings up ramming attacks but unless it's a near total car ban, one can always rent a car and use that for an attack.
He addresses environmental issues which cars do have a part in but the same applies to public transit with it being less cost (environmentally) effective the less passengers the train has.
Less efficient in cost and environmental damage.

More efficient in environmental and economic cost.
Economic costs are addressed but it's my money and I can choose how to spend it. If one bring up the greater infrastructure cost, then the urbanists will need to realize they can't have a train come every 15 to 20 minutes if the ridership is not dense enough.
I believe Jason was visiting friends in a weekday in the early afternoon and complained they didn't run enough trains to his convenience going to the suburbs.
That type of trip seems to be an absurd waste of tax payer funds so they will need to square that circle.
The topic of crime is brought up tangentially as City Nerd couldn't go into a local Walmart with a backpack.
That not an issue with cars, transport, or urbanism but crime. Singapore nor Japan has such serious problems.
All in all, the same irrational hatred of cars.
