"Force" could mean regulation, or it could mean that people are forced to decide based on what they can afford. The physics is inescapable. Myself, I take publc transit, even though I'm suspicious that it's really more energy efficient since the buses and trains are half-empty most of the time. Plus they don't include replacement costs in the fare, and are always lobbying the government for huge cash infusions to buy new buses, etc. I would prefer a nice fully enclosed single-seat recumbant motorcycle for all-weather driving, especially if it cost half as much as a sub-compact, was just as safe, and got 100+ mpg fuel economy. If the option were available I would switch instantly.

A decent-looking all-weather motorbike doesn't exist in north america. I'd expect something like this:

The Monotracer is actually larger than it appears in the photo. Other websites show the Monotracer with a different paintjob, and I have to admit it's ugly. It's as big as a full-sized sedan, and appears grotesquely oversized in the ass, with an ugly bulbous windshield up front, and handlebars instead of a steering wheel. If they made it shorter, single seat, no bigger than a motorbike with a fully-enclosed windfairing and a cool metallic grey paintjob and dark tinted glass it would look hot. But only amateurs have built them thus far, so that's what you get.
