" the city itself found that 30-50% of parking spots are unused." is preposterous on its face. Where are these spots? What days and times of days are they unused? For what duration? Are there reliable transit options to/from these spaces? No. Otherwise parking where it counts in Cambridge - within a short walk of the vast majority of units - wouldn't be such a royal PITA.

Also, no. For NYC, he was mostly on the public transit side (think airports and light rail). So, no. He was very much trying to fix what Robert Moses and his ilk wrought. He also knew that we live in the real world where stuff already exists. Or doesn't.

The thing is you're living in a fantasy world. You keep striving for perfect, as if we're building cities from the ground up from scratch. Except we're not. Let's be real. The T absolutely sucks. It just does. Rail, buses, commuter rail. It all completely sucks. And bicycling isn't realistic for most commuters for 3-4 months every year (and I say that as someone who rides nearly 365 days/year). People giving up their cars en masse in Cambridge just isn't a realistic outcome, sorry.
