You're right, Sparky. We ought to work on ways to cement our legal status on the roads. The reason that I'm a bit reluctant to petition our legislators for legal status is the fear that it might backfire on us.
The automobile is still king of the road. Motorcycles are pretty much welcome because they are able to keep up with traffic. Bicycles are barely tolerated. It seems that no legislators or regulators have been willing to stoop so low (yet) as to ban them.
But practically all other low power, low speed motorized vehicles are outlawed the moment they show up. The exceptions are few and far between. If we encourage official consideration of motor assisted bicycles, then we run the risk of being dumped into the outlaw category.
I'm not certain that this is inevitable. In fact, my own estimate is that the chances are roughly 50-50.
But it's a threat that we shouldn't ignore.
It's true that Arizona, for instance, has recognized these as legitimate, road worhty vehicles. but other places might put them in the same category as go-karts, for instance. And if they do, it'll be hard to regain the lost ground.
