(adsbygoogle = window.adsbygoogle || []).push({}); to drive the sports cars on raid or any other multiplayer map and remove death barrier on all maps ?

It's possible, you just have to know how to script it and the death barriers are gone if you use the code posted in the part 2 of the GSC managed codelist.

Code for removing death barriers was posted in managed code thread:

    

foreach(ent in getEntArray("trigger_hurt", "classname"))

	ent delete();
