It's like that always - small boats have to give way to large ones for example. Boats traveling through fluid, controlled by a relatively tiny prop, are in no way comparable to road-going vehicles that enjoy the static friction of rubber on asphalt. Additionally, all vehicles on the road are held to (virtually) the same legal standards, regardless of size. If anything, laws are more restrictive the larger the vehicle. Also, this is false: The vehicles have no priority at all, the people in them do. There are many parts of the country where it would be illegal to cross a road on foot (jaywalking), but entirely legal to do so within a vehicle.
