Thanks for the support. I am good at suggestions. AIs can make it realistic in terms of traffic conditions. Sometimes streets are a bit too quite... Tolls are good for RP servers as it is real and the server will be called realistic if it had it. I personally like tolls as it is realistic and puts into players mind to either pay the toll or waste fuel to skip the toll. If players never pays the toll, its the police's job. So more fun for policemen.
