A car, on the other hand, is not copied after purchase, so a copyright license is not relevant. A “license” (as stated above) is not a general list of conditions you have to agree on; it is simply a list of permissions for you to do what copyright law (and trademark law, etc.) would otherwise not allow you to do. No such law restricts what a buyer is allowed to do with a car after a purchase is made, unless a contract is signed. A contract can state arbitrary restrictions, but for something to be a contract, it has to fulfill a number of conditions: it must be knowingly and willingly entered into by both parties, it must not be unilateral or even, in some jurisdictions, too beneficial to only one party. Clearly your standard so-called “license agreement” does not qualify. Ideally, and usually, a contract is something on paper which both parties sign. Do you sign such a thing when “buying” a Tesla? If so, does this contract allow resale? Does the contract require the reseller to require the second-hand buyer to also sign it?
