The entire argument is "light rail is expensive." This is the most braindead argument possible. Light rail is only expensive because America demands every single aspect of every single thing be fully privatized. If the government builds the rail instead of contracting out wasteful for profit companies to build the rail, the problem of 'it is expensive ' goes away entirely. It just shows a lack of critical thinking when people say "we can't do it because expensive." The entire article is based on that entirely flawed premise. It is artificially expensive. Fix the root of the problem rather than trying to invent ridiculous solutions that try to work within the problem.
