Stick is short for stick shift. Blinker is an apt description. Gas is short for gasoline, which almost all cars run on. Commercial is short for commercial advertisement, and "advert" sounds like a bastardized piece of French.
So most of it is you Brits not keeping up with the abbreviations. 🙂
Plus you spell color as cal-loooo-or.
Nope, we spell it like the original french "colour"
