i think the best locking device is lock at ur brake pedal..... if u lock on ur steering,thief so easy to break out coz steering is soft and without hard steel inside to prevent hurt on driver while accident. brake pedal steel is very very robust,imagine if ur pedal broken to 2 pieces,it will be very danger...so manufacturer done the steel which is not possible to brake them down in short time....so if want to buy ur lock....lock ur brake pedal.....
