Rex, that may be in rural areas,
but in cities, auto insurance rates are much higher, there is more ridership to use mass transit, and more tax payers to share the taxes needed to fund mass transit. Of course taxes fund these projects. Now they also create jobs in not only their building, but constant upkeep, and those employed by them also pay income tax. Cause and effect, source and affect.
Japan has been doing it for a century already, as has most of Europe.
Cleveland has light rail, and Ohio has moderate taxes. Dallas has it, same thing.
Atlanta, same thing.
When you calculate fuel, insurance, tire wear, maintainance, and repairs from bad roads, it is not cheaper to drive to work every single day. Much fuel is also used sitting in traffic because of road repair construction. Two of our freeways are currently closed in one direction for over 30 miles each. Surface street traffic is stop and go, and also uses more fuel.
In Atlanta (Alpharetta) namely, it can take 30 minutes to drive two or three miles in rush hour traffic.

For now the future focus seems to be automated cars, most of which I suspect will be all electric.
