Police pursuits were a relatively popular thing in S1, just as something to break the tension and have some fun. As far as making it an actual mode, that's a little much, but why shouldn't the devs allow for a free roam ability? If it's a programming issue, then I'll understand, but if it's a "this is a sim" issue, then that's just stupid and ignorant. I agree it's a sim first and a game second, but it still is a game, and if people are going to have little police chases anyway, why not make it a little easier for them to have fun.
I also very much want to see point to point touge racing. It would offer a very different experience and off the drifters an actual course to drift. as opposed to the race tracks that only really offer very high speed drifting.
