>tolls are expensive

Well do you know what's expensive? Highways. In the US less than 20c of every dollar come from road tax/fuel tax/tolls. The rest is paid by taxpayers, whether or not they use those roads, whether or not they drive, whether they drive a 3.5 ton SUV or a 1 ton "small" car. This is not even getting into the terrible externalities that car use entails.

Personal automobiles pay far too little.

>tolls should cease after initial amount is paid

A good ballpark is every ~30 years you spend, in maintenance, the same amount of money it took to build it in the first place.
