Let’s not pretend that transit can solve for the needs of every single city resident. If the city has any ambition to be a melting pot for all, it needs to allow everyone to coexist. Some people will choose to drive, others will take transit, but to push one group out in favor of another will leave the city a hollowed out core once again... just like it was before the urban renaissance which began in the 1990s.
PS: If your main objection to cars is pollution, we’ll mosey on over to electric cars as soon as charging infrastructure gets off the ground. There’s only a smattering of Teslas in Manhattan, but soon enough there will be enough charging stations to get our gas guzzlers off the road for good.
