I live right outside NYC and have to drive through on a semi-regular basis. People generally do move out of the way of emergency vehicles. BUUUTTTT, traffic is completely fucked in NYC. Watch the video again, cars are trying to move but literally have nowhere to go. This happens daily, if you're not out off Manhattan by 3pm your travel time is now at minimum doubled on an average day. Some days its 3-4x worse.

As an NYC resident, cars will move over if there's space, but there's so much congestion that you physically can't move, there's no shoulder or anything.

And there's also idiots who are fighting congestion pricing that helps with these kinds of problems by reducing the number of cars on the road. You can't widen these roads without getting rid of sidewalks which just means even more cars and traffic so the only option is reduce the number of cars.

the right lane cars move to the right the left lane cars move to the left the ambulance goes down the middle, its interesting your brain only imagines moving right but not process the goal of creating a path
