In my opinion, this is actually a really interesting one. I've always been experimenting with getting pursuits by AI more intelligent, and would be really curious to see if there's like a RPH command to initiate a pursuit with yourself as suspect. To stop the pursuit for example, you can step out the car and the pursuit will end; everything returns to normal.
It would be a really useful feature for the modding community, as we can test officers' reactions to different situations. Currently it's a big struggle because you have to spawn in drivers, assigning them a task drive, initiate a pursuit on the driver NPC and when you are finally able to test out your mods, the NPC gives up quickly.
And beside this, it would also be really fun to have police officers chasing you. The game modifications and LSPDFR made chases much more organized and challenging for suspects, so it would be interesting to see them chasing you.
Big fan of this suggestion!
