Yep. I drove around in a VW van for several years without plates or registration. (I was extremely poor then.) The other trick was, but it no longer works as much, to leave dealer plates on vehicles and never register them... this loophole has been closed in most US states by requiring registration with dealer vehicle sale. Already, it was often required for the new owner to register a vehicle integrated as part of a private party sale.
