Hey, sounds a lot like my driving experience!  I picked up my '85 Chevy
conversion van when I was 20, and also did my fair share of dumb stuff in
it.  Once I dropped a GM crate motor into it and got about twice the power,
the dumb stuff started to happen at higher speeds:)  

I never felt close to rolling my van, but I almost endo'd my '78 Blazer
once.  I was also riding in my friend's S-10 Blazer when he was practicing
his rally driving - I believe the move is called the "Scandinavian Slide" (a
quick flick away from the direction of the turn, and then back into it - it
does a nice job of forcing the tail out, even on a vehicle that is prone to
massive understeer).  That one put the truck up on one wheel (the outside
front).  It was a pretty dumb maneuver, but honestly it could happen during
a last-second swerve around a road obstruction.

But safety factors cost money, and you need to cut things as close as
possible.  This is where you need to pay careful attention to test and
validation results, rather than just depending on analysis if you're really
trying to get your safety factor close to 1.
