Jasper Janssen said:Buses only need a few passengers (5 or so) to consume less than the same
number of people in cars (at 1 apiece, of course, as most of the miles,
especially in the US, are made), the same goes for trains with higher
absolute numbers.

If one examines the relavent actual fuel consumption per passenger mile
statistics, mass transit systems, even the most heavily used, in the US
get roughly the same passenger per mile fuel consumption as the average
car (ie gas guzzler) with one occupant, the driver. This is because
transit keeps moving whether anyone is using it or not, and the vehicles
are very heavy. And transit proponents never consider the fuel used
transporting replacement drivers around, which would reduce transit
actual fuel economy.
Cars are parked when not in use. Have a fuel efficient car (or carpool
or both) and transit can't compete.
If transit was so good, people would clamor for it, but people don't
want it unless driving is miserable. Here in Chapel Hill NC, transit is
FREE. Yet few "townies" use it, except those who are forced to by
increasingly restrictive parking on campus where they work. It is used
almost exclusively by students who don't have the option to drive. Many
routes are virtually empty during non-peak student times. When the
students are totally gone, the busses are virtually empty.
Further, when it became "free" (i.e. even more heavily subsidized than
normal), walking and biking plummeted. Close-to-campus bus stops, which
previously had few boardings, now have many boardings. People are too
lazy to walk or bike a couple of blocks. So, previous non-polluting
travelers are now "motorists," except they are chauffeured. And it makes
our local transit artificially look better than it is. If our transit
was populated only by people who would otherwise drive alone (rather
than walk, bike, or carpool), it's fuel consumption would be truly ghastly.
