I read the first few paragraphs, Just turn your wheels, shut off engine, lock the steering wheel by turning it to click, use steering wheel lock, pull hand brake, and lock your doors... that's what everyone should do to limit or at least make thieves waste more time on the car.
Someone could always tow the car and steal it, these insurance companies ARE the worse thieves ever.. and government gets their fair share. If you let people drive without insurance and apply BOND rules on everyone it would be different.. ahhh money.. it spins every wheel.
