even needed, a PAV could land right in the street, the only thing they would
need to do is clear all the trees.

I agree the noise issue could be resolved pretty easily. Landing in
the street is another story. Besides tree clearance, there are myriad
local ordinances that would probably get you jailed every time you
tried it, not to mention the occasional "slicing and dicing" of the
occasional pedestrian that wanders by. ;-)
