And the fact that everything was done almost entirely sans-cgi makes even more entertaining for me to watch.

The film wasn't even close to sans-CGI, although some of it was practical. "Fury Road" had some of the best uses of CGI in modern cinema, and I can say that because most people didn't even notice them.

Here's some comparisons between Fury Road shots before and after CGI was applied. So yeah, the War Rig wasn't fake, but a lot of vehicles were and were so well done you though they were also practical.

That's the tragedy of those working in special effects: when they do their job best is also when their efforts are most invisible.
