Is a good place to start ^.^ Most of these things are already available. Check out Traffic Policer, Wilderness Callouts and CalloutsV.

From what I can tell the player ped is given the TASK_OPEN_VEHICLE_DOOR task. The player is then given an animation to play and the suspect is given a LeaveVehicle task. Immediately thereafter the suspect is made to ragdoll. I don't think this is a built in function. TASK_LEAVE_VEHICLE(Ped ped, Vehicle vehicle, int flags) Flags from decompiled scripts:0 = normal exit and closes door.1 = normal exit and closes door.16 = teleports outside, door kept closed.64 = normal exit and closes door, maybe a bit slower animation than 0.256 = normal exit but does not close the door.4160 = ped is throwing himself out, even when the vehicle is still. 4160 is the flag used to make the suspect leave the vehicle, probably.

Same here ^.^ On top of that it would probably mess with LSPDFR's behaviour so it's not advised at the moment.

Correct. Speaking from GTA's nature the presence of such an animation is pretty much guaranteed. Something like this should be possible.

Exactly. I've had it work with the driver's seat; haven't tried with passenger seats though.

Most places you arrest them, indeed, and seize the vehicle.
