I may have given the wrong impression.
I don't wish to see bicycles regulated the same as cars. But if bicycles aren't considered “the same as” motorized transportation there will be no reason to claim a right to use the roads at some future date.
I actually feel pretty sure that our human powered machines will be around for another hundred years. And... that's several more decades than I need to worry about. But I do expect to see bicycles regulated more and more... ultimately limited to certain areas like the bicycle paths and/or lanes.
