If something isn't specifically illegal, it's your right to do it. There is no such thing as honoring the size of a vehicle. There are rules of the road, which include which vehicle has the greater duty to yield right of way to other vehicles, depending on the established rules of the road. No vehicle has the right of way either. Traffic statutes address who should yield to whom depending on the situation. Size never enters the equation. People who believe that because their vehicle is larger than another gives them the "right of way" are simply assholes with no understanding of traffic statutes. All this talk about speed limits can only be applied to roads with a posted minimum speed limit, of which there are very few.

Cyclists who ride in the road, yet ignore the rules of the road are just as much assholes as the people who think they own the road because they are in a vehicle.

I honestly don't understand the talk of licensing and taxes. It's just too dumb of an argument to merit any discussion.
