It is probably wrong of me to make this judgment, but I’m guessing that she had hefty substance abuse problems, and the DUI crash was just the tip of the iceberg.
Valid argument.
Even in the 80s, it could be assumed that heavy drinkers stopped there...and there was usually enough for it to end badly if it didn’t stop after decades!! Or one bad acccident.
Studies nowadays state that 10 to 30 percent (big range, I know) of heavy drinkers use the harder drugs (coke, meth, etc)
