The thing that gets to me is that when people are shopping for new wheels and the salesman (or should that be salesperson to be PC politically correct) mentions all of the cars wonderful electronic safety bells & whistles by their abbreviations, IMHO few if any ask the salesperson to explain them

HDA hill decent assist
CCVVT computer controlled variable valve timing
There are so many I can't keep up.
