I watched a traffic stop here in Memphis today and two partners were in different squad cars. I know the trainer has a follow function (haven't used it). But I didn't know how difficult it would be to set up the selected partner in their own squad car. I assume pretty difficult. Just asking.

I am not a big fan of having the partner be in a separate car, but I would like having a separate car assist in the traffic stop if needed, or even having 2 officers pulling over 2+ cars. That would be really neat and very enjoyable.

There are some problems with this sadly, as the GTA IV is as it is. The assisting car would most likely be extremely lethal to the fine citizens of Liberty (ramming people, cars, poles, buildings etc). It's a good idea on paper, but actually excecuting it is another thing. 

I can agree I guess I was meaning what theninja35 was saying, basically assisting in traffic stops

Since the bike mod was created it made me think of this topic, I was playing with the native trainer and can spawn a cop as a bodyguard and have him follow in the cruiser but he wont turn his els lights on like the bike mod, any ideas?

This would be cool for the k9 script. You can do it like k9 unleashed Broward County, where there's a deputy with the dog in a marked k9 unit and a detective in an unmarked unit

Now that would be cool
