Non-motorized wheelchairs operated by obese 90-year-old people are also vehicles, and they clearly don't belong on the road (hope you agree), so "vehicle" doesn't matter. The same goes for little battery operated kid toys and traditional kid tricycles. Most bike riders are far closer to the above than they are to cars. Lots of people are obese, elderly, and otherwise lacking in athletic ability. If these people are excluded from the sidewalk, then they are entirely excluded from the benefits of bike usage. The trouble here is that bike-related laws are mainly influenced by people who are extreme bike users. These users want to be in the road. They care enough to join cycling organizations that will lobby to have bikes treated like cars. The typical bike user is a physically weak person, and they ride on something like a $39.95 bike from Walmart. The bike has overly thick knobby tires, unreliable gears if any, big fenders, and lots of low-quality (thus thick) steel. You're saying these people have no right to ride bikes if you insist that they go on the road.
