The laws have to change. We have to start by dropping the concept of "street legal".

We shouldn't have to license a canoe. (at least in my state)

You get the picture.

The picture I get is one of mad-max style vehicles without
any exhaust controls spewing tons of blue/black smoke into
the atmosphere. I like controls on what motorized vehicles
can be driven on a road.

I have to agree though that a human powered vehicle, such
as a canoe, should not require a license.

I think they require a license to make them more difficult to steal.
