Where can one find the data to support your claim?

I can't prove what Tegger said and I doubt anybody can - until black
boxes are telling the story.
That's probably coming as a defensive measure by the auto mfgs.
I've never had the problem of mistaking gas for brake.
But though you and I may have trouble imagining that happening, it
makes sense. Especially since SUA predates electronic throttles.
Here's something that happened to me, and though it doesn't fit in
exactly with SUA, it's similar.
My kid converted his '93 Corsica from auto to a 4-speed Getrag.
Shortly after he did it, me, him and my wife went somewhere in it and
I said "I'll drive." Just for the hell of it, and to make him feel I
wanted to try out his handiwork. I didn't give a shit and thought he
was stupid it do it, but hey, I knew he would like that.
So I run it up to second gear getting to a stop sign, and I blow the
stop, ending up halfway in the intersection because I couldn't stop
it. Luckily it's a residential street with little traffic.
Turns out he had some big stupid aftermarket pad on the brake pedal
that put the right edge real close to the gas pedal, and my foot was
pressing both pedals.
Seems simple enough, but I had enough of a WTF moment that I ended up
in the intersection. You could call it a brain fart, but I cussed and
told him to take that crap off the brake pedal.
Still don't understand exactly how that happened, but for sure my head
wasn't in gear with my foot in a new pedal configuration.
I actually had to look down at my foot to figure out what I had done
wrong.
I was okay with it afterwards, and he never changed the brake pedal
pad, because he never had trouble with it.
But that WTF moment gave me a glimmer of the kind of confusion these
SUA drivers suffer from. But just a glimmer.

My memory is fuzzy, it's been a while since the Audi 5000 UA issue,
but as I recall it was the first generation of Audi with an idle air
bypass valve, or some such, and as such it allowed the computer to
control, to a limited extend, the "throttle". The Audi's mainly did
their UA at low speeds/stops which always made me think it was tied
into the idle bypass. Other then sticking pedals on mechanical
linkage, and usually after someone has monkeyed with it, I've never
heard of UA on a true manually controlled throttle, other then simply
stepping on the wrong pedal which no doubt does sometimes happen.

As I recall they pinned it on the pedal config and changed that.
I didn't follow it closely, though I think the mess was initiated here
in Chicago when a woman came roaring out of a parking garage and ran
over some people.
Never cared about getting an Audi anyway.
And I probably will never own a Toyota, but this is much bigger news
so it's hard to not know something about it.
Beside that, it's got me looking into what they're doing with this
drive by wire stuff, which isn't Toyota specific.
And I notice the EPS problems aren't limited to Toyota, and there are
a lot of Cobalt complaints. My wife wanted a Cobalt as her next car,
and now maybe I can talk her into something else without electronic
control into throttle and steering.
If such a beast will even exist when I'm ready.

ultimately I think we will all be in electric cars, even performance
cars. So most likely everything will be electrically driven.
