No person driving or in charge of a motor vehicle, except a commercial motor vehicle, shall allow it to stand unattended on any highway, public street, or any other public place, or on a parking facility open to the public use, without first stopping the engine, locking the ignition and removing the ignition key from the vehicle. The registered owner of a vehicle found in violation of this section shall be held prima facie responsible for any such vehicle. Violation of this section shall not mitigate the offense of theft of such motor vehicle.
