There aren't enough street spots for many residential areas even with permits. We don't have any really large self-park garages in the city for people to just pull in, pay, and not be circling around looking for a spot. And developers won't construct them as it's not profitable.

Could maybe ban street parking for out-of-state plates (permit them to park at garages + private property) or allow them to park at certain hours? Maybe take away the licenses + cars from drivers who have caused multiple accidents or have been caught driving recklessly a few times? Or have a more difficult requalifying exam for drivers who have had x years of experience and/or at certain age? Maybe have congestion pricing and have different rates for out-of-state plates vs. plates registered to a NYC address?

Could also do other things such as change the timing of shift changes. Example: nurses at all the hospitals (to my knowledge) do 12-hour shifts starting/ending at 7:00am/pm. Could have the hours at nearby hospitals staggered so one hospital does 8am/pm shift changes and the other one does 9am/pm?

Could also do a dedicated SI-lower BKLYN-QNS underground roadway that trucks get a dedicated lane or two where once you're in it, there's no way to get to Manhattan? It'll alleviate a lot of the traffic on the BQE.

There are many ways to address traffic, but it's going to require great ideas, the willingness to implement them, the money to do so, enforcement, etc. No one's going to be happy with all of it (see the Brooklyn Promenade right now), but it'll have to be done sooner or later.
