Yes, it is very good, due to its complexity, realism dosn't count for much then.
Nice to see another well made complex crash car(bus, whatever), instead of all the textured ones.
Sadly, I cannot up the precision at the moment due to the limits of the For loop used to compile the vectors. There are longer For loops out there, but I need to access the loop count and as far as i know, that is not possible with them.
I will, however, look into an alternate script design to try and accomplish this, but it will be more cluttered.
