I'm just curious about how your registration systems all seem to be so complicated. Is this a correct assumption or am I over simplifying?
Where I live in Queensland, Australia our system works like the following. you need a recipt to prove you bought the car, this can be hand written or a dealer recipt, and a Roadworthy cirtificate to prove it is safe to drive. Vanity plates stay with a person, or can be sold. non vanity plates stay with the car. You then register the car or transfer the registration both of which need to be done at your department of transport office or if your town does not have one the local police station. Someone looks over the car to check it for details such as vin and engine number, and then looks at the Roadworthy and comfirmes the details and that it hasn't expired. If it is currently registered and they are happy you can drive away and you get a form later to say you are the new registered owner. if you are a new owner or you need new plates as it had vanity plates they will give you a tempory sticker to put on the car untill your new plates and sticker arrive by mail.
One a year you pay a registaion fee, which includes compulsary insurance to cover damage your car does to 3rd persons or property, and then they send you a new sticker for you car to prove that it is registered. From that piont as long as you are the owner of the car and keep paying the registration fee, you never have to prove the car is roadworthy, but you must maintain it that way. If you get pulled over by the police they can check if the car is registered by calling it in or checking they sticker, and if they feel it is nessary they can "Defect" the car. Which means you cant move it except under police supervision or on a flat bed tow truck as they think it unroadworthy and therefore unregistered and it is illigal to have an unregistered vechile on public property. You then need to get a roadwotrhy done to prove that it is Ok to use.
