It is always, always, (did I say allways?) the vehichle operator's responsibility. Look at the sales brochures, look at the mnf website, look at the contact or purchase agreement you signed, they will have that statement/disclaimer somewhere. The "but so and so said it was ok" defense doesn't work in the principles office when Jhonny says "But Billy said it was OK if I threw a rock at the teacher" And it doesn't work when you grow up either.
When you become of adult age in a state you become (supposedly) responsible for your actions.
Remember whay your mother used to say about Billy? " If Billy told you to jump off a cliff would you?" I just don't understand people blindly "jumping off the cliff" because Billy with the pretty grin that said I look soooo young for my age and bought me a can of soda pop said it was ok.
