Yeah I was thinking that one thing that would keep the tolls down would be that the point isn't to charge for the roads but to charge for the automobiles. But Wormguy has a point, and any private road construction is probably going to have only a tangential relationship with the auto industry after a few years. There goes their reason to discount road uses.
So now we've got a world where the costs of road usage are no longer hidden but paid up-front. What happens?
Development will be higher density and built closer into the cities. More mass transit and earlier investment in better mass transit (subways and high speed rail.) Edge cities and corridor cities form. Houses are smaller and closer together to maximize profit on the more scarce "good" land. Therefore utility bills are lower and commuting costs will also likely be lowered (now that all the costs are out in the open, people can make better decisions for their pocketbooks.) Wow, could this butterfly debt culture? It's possible.
This might help keep wages lower for longer and therefore keep inflation down.
Population isn't going to spread out as quickly; the booms in the South and Southwest won't happen. The Florida boom still might; real estate was a local moneymaker, so I'd expect good state support for roads to emerge there. The Southwest is too vast though, and Phoenix will remain sleepy and unimportant.
States will likely pick up some slack on roads for the public good; at least regulating how the road companies build and maintain. I can see early cooperation in places like the Northwest to subsidize an alt-I95 to try to keep costs low.
Right, I'm well aware that that was a flight of fancy worthy of a
50s Disney cartoon
(God I hate that freakin cartoon! I didn't need Stachiatos' masterpiece to convince me a Disney-run world would be evil.)
Anyway, feel free to rip that all apart, I'm curious what people think.
