After the countdown to start, turn the car around and drive in the opposite direction. Go to the first road on the right and follow it. Try not to get hit by the cops, as it will slow you down. A short distance up that road is a parking garage on the right. Go inside and go all the way to the top level. Try not to have any cops follow you. You can go the very top level and just park at the corner. The cops will not go up there, and the timer just keeps ticking.
