The current GM computer in the Olds Aurora records several
items that could be considered abuse.  For example, if you shift 
into gear, from neutral, with the throttle open (i.e. neutral drop 
the car), it logs a code.  If you look in the factory Service Manual,
all these codes are explicitly defined.  There's probably 20 different
codes for driver abuse of one form or another.

I'm guessing that somewhere there's a 16-year-old kid who's gotten
himself in a pile of trouble for beating the old man's Aurora, after dad
had the car in for service and the dealer informed him of junior's
antics
with his $30,000 ride.  :-)
