If you're gonna outrun the cops, you need to do it quickly.
When I first got my car, I was racing a Ford Contour SVT going like 80-90mph, when i see a cop on the median. After I passed him, he started pulling out, I kept accelerating, the road curves, I slam breaks, turn into a neighborhood, get lost and pull into someone's driveway, turned lights and engine off, shat bricks and waited. After a few minutes I went home.
I may not have exactly outrun him in a chase situation, but I did lose him.
