Classifying Pedestrians, Bicycles and Motor Vehicles
It's easy to separate motor vehicles from bicycles and pedestrians --
just use those spikes like in gated communities. *Cyclists can slip between the spikes or stop and step over them as can pedestrians. *A motor vehicle will get 4 damaged tires. Separating cyclists from pedestrians is trickier. *The first obvious solution would be to install parallel bars like on cattle stops on sidewalks/pavements. *A good wheelman, however, will just hit these at an angle like he does oblique railroad tracks. *Maybe some combination of patches of ice and grates would work but that would be expensive to install and maintain and dangerous to pedestrians as well. Moreover the weight of a cyclist + bicycle averages about that of a pedestrian, What? What distinction are you drawing between a cyclist and a pedestrian? More to the point, why? both an order of magnitude less massive than a motor vehicle. *Even more compelling a motor vehicle often represents 2 orders of magnitude more kinetic energy. As a practical matter, is there really any reason not to reclassify cyclists as pedestrians as far as cycling on the sidewalk/pavement is concerned? Yes. A bicycle is a vehicle, not a pair of feet. Some kids' shoes have small wheels in the heels. True, but what point is it you are struggling to make? A person riding a cycle is a cyclist (at that point) When does a pair of wheels become a bicycle? When a drive chain is added? It's wouldn't be hard to snarl up the judiciary as well as uk.rec.cycling with a lot of inbetween designs. Gun nuts use the classification/camels nose approach all the time with great success. Some guy in Florida realized he would have to pay a bigger fee to register his floating dock as a dock than if he registered it as a boat so he registered it as a boat. My father once got an article in _Reader's Digest_ about a Navy man who couldn't get the Navy to pay for moving his canoe across the country. He filled it with dirt and flowers, called it a "planter" and the Navy was ok with that. Bret Cahill |
