> For some odd reason politicians and many people are hung up on light rail and it has the worst cost structure of all mass transit options.
For many people, Light Rail (or trains / subways) are the only decent mass transit they have ever experienced in the US.
Every single major and minor city has a bus system. Most of them are nearly useless, often intentionally so by design. It's natural for people to demand something useful, and light rail is nearly universally more useful than busing (including BRT) in any given market.
> It isn't flexible and its cost per mile is staggering let alone the cost of maintenance.
Those are benefits of light rail, not drawbacks. The higher costs and inflexibility of light rail represents an authentic long-term commitment to good useful transit in that area.
To replicate that value with a Bus system requires you to build grade separated, dedicated right of way. Which is where 90% of Light Rail's cost comes from. So if your going to spend that money, you might as well put in real Light Rail and get all of the benefit.
