Of course, "riding" itself might be a problem on any two-wheeler if you're somehow injured, which is why even the much-reviled SUVs and high-clearance 4WD pickups might turn out to be more useful than a motorcycle, at least in the short run. In the long run, self-reproducing transportation is likely to be the future answer, just as it was before the Automotive Transformation. Whatever their other drawbacks, hayburners like horses at least don't need batteries, gasoline or air in their tires. WIRED being a magazine for technogeeks, our equine pals didn't make their "vehicle" list; but they're on mine, as indeed they might be on the lists of the other moto-journalists who, like me and CW Senior Editor Paul Dean, attended the 1975 Kawasaki new-model intro at Incline Village, Nevada, when Kawasaki PR guys Dan McCue and Doug Freeman told us all to be "ready to ride" early on the first day—but didn't tell us that we were going to ride horses at the Bonanza Ranch before we rode the latest Kawasakis. The sight of a hardcore MX racer sitting on a Western saddle—Scott plastic Star Wars boots slid into stirrups and MX gloves holding the reins as the boots' owner looked miserable—has never left my memory. Nevertheless, there's no question that the horse beats the bike in terms of long-term sustainability in the absence of an industrial infrastructure.
