Car thing is probably a bug. Do you have other mods installed?
Nope. Just that. Poorly, probably.
In fact, just to make sure I hadn't screwed that up, here's what I did {again. I think.}.
Install Fallout 2 {fresh, unpatched}.
Extract Update 4 to an unrelated directory.
Extract Update 5 into Update4\Data. So now the Data folder has a Data subfolder, which strikes me as a bit odd, but that's what the instructions say, as well as not seeing any difference if I overwrite Up5 over Up4 {Klint doesn't give new dialog, no TeamX logo}.
Extracted the 5.1 patch to Update4\Data, overwriting if necessary.
Update4\Proto files and subdirectories set to Read Only.
Copied the entirety of Update4 into the Fallout 2 folder. Only Fallout2.exe got replaced.
------------------Post-instruction messing around
At this point, the Fallout 2 folder looks something like this.

Lots of redundancy between folders in the Fallout root and Data folders, but then again, that might be intentional; the .exe, afterall, got changed too.
Something defintely got modded, as I see the TeamX logo on new game start. On the downside, upon entering the Arroyo temple, the map draws a complete blank.
Backup of the entire Fallout2 folder and moving of Art, Maps, PCX, Premade, Proto {ROed too}, Readme Files, Scripts, Sounds and Text folders into the Data folder.
Actually, in hindsight, doesn't that overwrite Up5 right over with Up4 again? That might explain the other problems I've been having.
How the flaming heck do I install this mod correctly?
{impending edit on the results of extracting Up4, moving all the folders in it into the Up4\Data and overwriting the contents with Up5 and fix}
Edit: Oh, for heaven's... how the hell do I install this? I'm really stuck for ideas at this point.
