(a)   No person shall leave a motor vehicle, except a commercial motor vehicle, unattended on any street, alley, used car lot, or unattended parking lot, without first stopping the engine, locking the ignition, removing the key and taking it with him or her; provided, however, that any violation of these provisions shall not mitigate the offense of stealing such motor vehicle, nor shall such violation be used to effect a recovery in any civil action for theft of the motor vehicle, or the insurance thereon, or have any other bearing in any civil action.
      Whenever any police officer of the City of Flint shall find any vehicle standing in violation of the foregoing provision, such police officer is authorized and directed to issue a traffic summons for the violation and then remove therefrom the keys left therein and deliver the same to the Officer in Charge of the Patrol Division at the Police Station, or to impound said vehicle, at the direction of the Commanding Officer, in the event that the ignition is left in the unlocked position with no keys.
   (b)   No person having control or charge of a motor vehicle shall allow such vehicle to stand on any highway unattended without first effectively setting the brakes thereon and when standing upon any grade without turning the front wheels of such vehicle to the curb or side of the highway.
