Lowejackson- Heh heh, I understand completely. Guess I've turned some kind of corner now that I think primarily in terms of automatic transmissions

Gee, who woulda thunk it!
I will grant that in the past there were automatics where everything relied on a small pawl/pin and these suffered failures, so back then it was wise to also use the parking brake.
Guess it's a toss-up these days, but if you're gonna use it, you gotta *use* it so it stays functional; had my wife had her parking brake problem anyplace except in the dealership's parking lot it woulda been a *big* problem indeed!
