I have noticed that motorized scooters have been granted a status in some places of "absolutely magical". It is apparently legal to park them at no cost at bicycle racks, even if they prevent actual bicycles from parking there. They are, by association, legal to ride (or at least, push) on the sidewalk as well. You can carry whatever or whoever you want with you on it, seldom need a proper helmet, and if you have enough power you can go ahead and drive on the freeway as well. They generally need less insurance and registration to boot.
Why bother with a bicycle at that point? We don't really embrace fitness in this country anyways.
