Oh yeah I see the problems with it. I just think it's an interesting element that isn't often seen. What I would do (if I could create things from a whim) would be to have it in there, just make it to where you could drive around Gazala 5 or 6 times and then get low on fuel. But with all the things the game needs (Russia, more Russia, even more Russia), it would be a waste of time to even think about. But, it would be cool.
And true that about not living long enough. We were being very careful to not get too close and really work together, which is why we lived for so long (well, the main factor was we were fighting the AI, which even turned up quite high still isn't too much of a challenge).
I would love to see something like a gearbox failure or tracks coming off from a hit. Along with something like aileron failure on a plane (reducing the roll speed) and other things like that. However I'm pretty darn sure those things aren't possible with this engine.
