He's using the colloquial definition of "3", not the mathematical one.

is it proof or evidence?

please show me where he saw 3 changes in one day...

Sorry, 3 prices not 3 changes.

Some states suspend gas tax as Americans feel pressure at the pump

Gas in Vegas $5.36 a gal.  More than Hilo.

Been 11 days since the last change at the pump I pass daily.

$4.45 in Tucson

I'm more of a Mustang purest.  the Mach E isn't a Mustang to me.  it's a SUV, 4 doors, electric, so not a Mustang in my book
although its a very good car, with those 1st gen issues like you said.
very good car, I just don't like how Ford execs market it, calling it a Mustang and giving it Mach status. 
2023 will be the last year of the Mustang with a V8 motor.  and that's sad to me.  they are going to castrate an American Muscle car icon to be compliant to the green earth movement.  I think they will still have V8 in specialty cars, but the Mustang is by definition a free roaming horse of the United States, or what it was named after the P51 Mustang Military fighter plane of WWII.
It will be a sad day in History when they don't make V8 Mustangs anymore

I had this video sitting around for over 50 years.

Those were the days, huh?

When I was 18, I built a "66" LeMans w/326 Hurricane small block bored short of 400, Borg Warner T-10, 40lb Fly, 3 prong clutch, Wildfire coil, 50's and 60's Mickey T's, Thrush headers, Ladder racks, etc... 
Still got 17 MPG when driven NORMALLY 
1988 H&E XJS 12 cylinder, gets17 MPG when driven CONSERVATIVELY, other wise 15MPG.
My 2007 F150 FX Super cab gets 17 MPG when driven NORMALLY 
Not alot of progress in 56 years IMHO
Don't drive the Jag much but wish I still had the Lemans
