The comparison to current public transportation is unfair. First, imagine what public transportation would be like today if as much money had been invested as has been invested in cars. There are more licensed vehicles in the U.S. than there are licensed drivers.

Cars simply cannot beat public transportation in raw material use, operating cost or road space utilization. My car occupies 70 sq ft of road space. At most, it can fit 5 people. That's 14 sq ft per person. A typical bus uses half that (calculated from an MCI D series). Since raw material use is more dependent on the volume, the savings will be even greater there.

My car gets 30 miles per gallon. Fully loaded, that's 150 person-miles per gallon. A fully loaded bus beats that even if it only get 3 miles per gallon. However, since buses run standard routes, they can be wired directly to the power grid, eliminating the need for separate fuel and eliminating the need for the batteries than an electric car needs.

And this is with current technology, developed despite substantially more money being spent on cars and highways.

The reason your commute is faster with a car is that there aren't enough buses/trains. Vehicles with dedicated routes (such as trains and buses driving on bus-only roads) don't get caught in traffic. If they were comparably common, there's no way you could beat them on time either.

Honestly, I do this all too often. What if the American passenger railroad system had never been left to die? What if the Big Three hadn't bought up streetcar services all over the country and run them into the ground? What if we'd been investing money for the past half century in making advances in new rail technology instead of trying to make dangerous cars slightly less dangerous?

The intermittent dialog about high-speed rail here brings to mind an obese diabetic who has resolved that he definitely needs to start going to the gym one of these days.

Ok, I think I'm done ranting.
