The anti car people are gonna give you the same talking points , cars are bad , it's causing health issues, just bike everywhere, take public transportation, just use Uber or lyft. Reddit will say they are pro bikes Lanez but do not trust reddit opinion as the city consensus. Also it's 8 million ppl not including tourist ( traffic will happen regardless of mode of transportation)

Nyc major issues is that everything transit directs to Manhattan below 125 street and parts of Brooklyn. In my personal opinion I think bike lanes are ok, but with the incoming gentrification people may feel it's to get the poor's out. ( Metro north in co-op city)

Also remember most of those who commute are mostly in two camps, rich ppl from Conn or NJ who refuse to live in nyc or the service workers ( who can't rely on the subway to get from the other Bronx to lower Manhattan all the time) ( we need cbtc since yesterday)

As for the Bronx well they gonna bulldoze all the houses for apartment buildings
