As for licensing, I feel it would be a serious civil rights violation to regulate who can use public roads and who can't. I can appreciate the need for licensing drivers of motor vehicles because motor vehicles are particularly powerful and dangerous machines but that doesn't extend to bicycles. It's like, we might require someone to be licensed to operate a backhoe, but that doesn't mean they should need a license to use a regular shovel.
