The metropolitan area covers about 2000 square miles.
Even the biggest plan proposed by Metro would have less than 75 miles of track at a cost of $8 billion serving 1% of commuters, nearly all of whom ride buses today.
We would actually save money by buying each rider a new Lamborghini.
You nailed it. The long commute times aren't in the central city. Why build something just within the 610 loop and expect it to handle Houston's transportation needs for the next 10 years?
