Just wanted to ask; what exactly is the core difference/differences between this and the Police Pursuit mod?

They appear, at least from the YT videos, to be almost identical.

You should give both a try. You'll notice quickly ;)

I already have LCPDFR installed. It's the one intend to stay with unless you are saying the other is a better option?

Police Pursuit offers more content than LCPDFR at this point, at least in my opinion, but LCPDFR is more realistic. You typically don't go from stopping a drunk driver to preventing a nerve gas attack on LC after a couple of callouts, but it's all good fun. It's pretty odd that the mod takes away points from you if you break traffic laws, since it seems like realism isn't that much of a focus anyways.

The other weird part about that is I'm pretty sure lights and sirens exempt you from traffic laws. I can't imagine a cop getting in trouble for running a red light on the way to a call.
