tx tried to do this with a toll road and everyone just avoided it, so the chinks that owned the rights kept raising prices until even the rich people didn't want to use it. so they went bankrupt and the state took it back and made it a regular tollway. but the added bonus is all the extra traffic through little towns trying to avoid the toll road gave those towns such a boost in revenue that they upgraded their highways and now everyone still avoids the toll road and gives more revenue to these small towns.
