Except as provided in Section 1630.5, a printed contract of bailment providing for the parking or storage of a motor vehicle shall not be binding, either in whole or in part, on the vehicle owner or on the person who leaves the vehicle with another, unless the contract conforms to the following:
A copy of the contract printed in large type, in an area at least 17 by 22 inches, shall be posted in a conspicuous place at each entrance of the parking lot.
Nothing in this section shall be construed to prohibit the enactment of city ordinances on this subject that are not less restrictive, and such enactments are expressly authorized.
