Good that you're being creative, it's easy to get carried away!
The pursuit servers come and go mate, so there's not an individual permanent Pursuit server I can recommend at the moment.
Someone has since informed me, that a lot of the canyons servers
become pursuit servers, with supercars pursuing other supercars... Most of the time well above the speed limits. A lot of people are not observing the speed limit signs I put in, instead only using them as brake markers!
You may see some of the ACTR server admins patrolling their servers in my Police Mustang skins, but for now, that's as far as any pursuit scenarios go. (A clever way for them to enforce their server rules)
