Related, one of the approaches has you in this truck. I was confused why there was 5 spots for the multiplayer character, but this is actually so the cutscene can reflect whether someone went in the passenger seat or not. The scripts *try* and reflect where you actually were sat.

i seriously have more issues trying to quick join to get a quick 10-15% than the mantrap at this point
just infinite loading, or people infinitely joining

Also fun to see the characters as they walk off which isn't normally visible.

You can also see their hierarchy of sounds where they build up sound effects from many pieces.
Again, we can compare to CodeWalker's equivalent (which also gives a clearer view on this particular sound)

You can also see a map of ambient zones, rules, and emitters. Which is fun because we can compare it to the audio view in the CodeWalker tool :p
