Here in Virginia we tap developers for the cost of roads ~ you, as a buyer, pay that.
We continue to suffer from years of neglect where local politicians imagined that if they didn't build roads that would stop development in its track.
BTW, that doesn't work at all. You end up with massive development and 2 lane pea gravel and tar roads.
You need to learn how to figure out their motives.
The Dem in charge of my county during the peak development years that he supported fully said the same thing, that building roads just encourages more development, all while he supported tens of thousands of new houses being built here..
That argument makes no sense, it's like saying the cart pulls the horse.
The reason why these libs encourage massive development without the required road work is to build voters support for public transportation at taxpayer expense, the LAST THING I WANT HERE.
