My 1993 BMW K1100 had a catalytic converter, as well as anti-lock brakes, as does the 2000 R1100 model that I drive now. Way ahead of the curve on safety and emissions. Almost all of them have secure hard luggage also, for carrying stuff. And shaft drive for minimal maintenance. An excellent car replacement, if not cheap to run. However, a 45mpg motorcycle is a pretty good way to reduce one's carbon footprint, not to mention one's parking and freeway footprint too! (I often split lanes here, where it is legal).

I admire all of you who can go vehicle-free, but for some it is just not yet practical. I wish our government were wise enough to phase in a carbon tax over time, to reduce fossil fuel usage and CO2 emissions, as well as to fund better public transport and vehicle alternatives. Some day it will be necessary, but obviously it won't happen in the next few years.
