That is entertaining. A couple of things were things I didn't realize were "SoCal" things.
I guess "blinker" for turn signal is an east coast thing; I say blinker although many in SoCal do say "turn signal"
I have never been asked for my "license number" when being asked for my registration or VIN. It's always "license and registration please"
We don't call our money "bills"--yes, the paper notes are called "dollar bills" and they are "bills" but saying "bill" alone would suggest an invoice. A check is only an invoice at a restaurant. Otherwise it is a bank check from a bank either written by you or to you for deposit.
Funny about "insure" vs. "ensure". Ensure was never always a word, at least not in the American dictionary. Insure can serve all usage purposes and ensure was basically created for an unknown reason. I have seen "ensure" in dictionaries recently. I use insure but I think most people actually use ensure unless speaking specifically about insurance.
No one says "beverages" for drinks. You only see than on menus. "Drinks" work fine. People will think you are a space alien or cyborg if you say "beverages".
I have never seen or heard an earthquake referred to as a "temblor."
The letter "Z" is pronounced "zee", leading to product names like "E-Z Kleen" or "La-Z Boy" (I still read the latter as "Lah-ZED-boy" after all the years I've been here).
Now this is just stupid. I always thought that pronuncing "Z" as "Zed" was totally ridiculous and pointless. Plus, it kills all the great puns that can be achieved by substituting Z for words that end in "sy" or "zy"! La-Z-Boy is supposed to be a pun on "Lazy"! La-Zed-Boy? Are you kidding?
I have never been confused when someone says Z. I have never thought it sounded similar to C. Drop the -ed! I think it's funny when Jeremy Clarkson refers to the ZO6 as the Zed-O6. How about the 240 Zed? Arrggh!
Slough is usually pronounced as "sluff," as in "slough off"
