Actually, don't take the first exit. That is what most officers are trained to expect that.(a "friendly" lady sheriff told me when she was doing paperwrk on my dad's motorcycle wreck, and my next door neighbor is a cop.)Take the second or third exit. And since you are going fast enough to run anyway, that shouldn't take too long. BE CAREFUL. If you wreck your car, it is a sure bet that you'll get arrested. A quick trip to the emergiency room, then you get a shiny pair of bracelets. Also, if there is a chance that he has your plate #, pull over. the chase is already over. And remember, cop cars DO HAVE CAMERAS.
BTW, my cop neighbor (who street races way more than i do) gives most people to 80mph in a 65.
