Trouble with script AI

Hi! I'm trying to set up a scene for a cinematic video I'm working on, and script AI is not really working the way I want it to.

Basically, I have a bunch of traffic cars (19 of them, plus a "camera car" in front) with AI paths, and I want a lead car to weave through them while chased by a couple of police cars.

I can drive the lead car manually, but since I can't drive multiple cars at once (and multiplayer, which I've already tried, has too much desync with this many cars spawned) I need script AI to drive the two police cars.

But, no matter how fast I drive while recording the paths, the AI fall way behind and, because they're no longer timed properly with the path, crash into the traffic cars the path was supposed to avoid.

Is there a way to get the AI to stick more closely to my original inputs, or even (though I don't think this is possible) just drive all three manually by "stacking" replays? (As in, driving one car while recording a replay, then somehow loading the replay and driving another car while it plays).

Any help is appreciated; if I can't get it to work I'll have to either scrap the scene entirely or record in small, awkward to work with segments.

 

Yeah, I noticed that in the patch notes - I'll be trying it out in the future.
As for the camera path editor, I use that pretty extensively already - I just prefer the natural suspension movement of a camera car for certain shots, since it adds sort of a cinematic feel.
