It’s also far easier to do this at 3 am when this video was taken. I’m sure this was done on the major N/S roads which are likely to have preferential flow treatment vs cross traffic. Try doing this in the middle of the day and you’re gonna have a bad time.
Also, keep in mind Manhattan has traffic lights at literally every single intersection.
Not saying this isn’t oddly satisfying but it wasn’t some kind of traffic sorcery or anything.
