- Yes, a motorcycle offers some advantages over a car. It also suffers
- several disadvantages in bad weather. It becomes markedly less safe
- and comfortable on wet roads. Also, few motorcycles really achieve
- high MPG ratings because of poor aerodynamics. Enclosed, streamliner
- bikes are possible, and have been built for specialized uses, but they
- aren't mass market material yet. The primary demand for power in a
- vehicle is to overcome air resistance at speeds over 30 MPH.
-
- Crash resistance is a real issue. With a car, even an econobox, there
- is a lot of crush volume to absorb energy in an impact. On a motorcycle,
- *you* are the primary crush space. Over the general population, it is
- unlikely that the increased agility of the motorcycle will negate the
- increased likelyhood of serious injury in the crashes that do occur.
