Proximity to a station is key.
In the US we most often build large suburbs spread out over great areas that are seeming popping up over night.
Now think of other nations like japan, who build the same about of homes in less than 1/3 of the space sometimes...
Higher speed internet in places like NY,NY should be happening... youve literally got little to no excuse... But running the cables to my house and all teh houses in the area is simply not very cost effective at the moment.
Some of the other coutries with higher speeds also have this problem in rural areas.
