To drive through cars and stuff,press the z botton.it will make you start blinking and then you can drive through cars and signs and stuff.dont do this during a police chase cause the busted bar will go up really fast and then you will have to pay for your car again.and if you hit a pursuit breaker(i call it cop killer)and there is a road black a couple of seconds away from where it is,then hit the pursuit breaker and then if you didnt drive past the road block,then you can drive right through the cars in them(also works with spikes if you do that on accident)
