are you guys nuts?  pull the plug and try again?  in another 10 years, the cost will be triple that cost now.  we need this project not only for its transportation aspect but for affordable housing, quality of life issues and lessen the need for being dependent on cars.  we have limited space and can't be building more roads.  and more roads will encourage the ownership of more cars.  driverless cars will not solve our transportation problems, it is small, expensive, and takes up space on roads.  the new jersey project should be a lesson learned, they pull the plug but now the people still believes that is its a worthy project but now will be paying much more?  to give up now is foolish and stupid.
