I have had this problem....
I TOOK my right foot and put it under need the accelerator and lifted up.
It work and didnt stick anymore.
Got lucki i guess.
SUPER SCARY.
Listen up everyone, if your car starts accelating on its own, push down on the brake, hard!!!
That's all, one step, don't worry about neutral or anything else.
There are almost no cars on the road today (probably none built after 1980) that have enough engine torque (even at full throttle) to overcome the clamping force of their brakes.
Try it if you don't believe me, just mash the gas at any speed and keep the pedal floored while you hit the brakes with your left foot (please practice in a safe, open area). Your car will stop in a fairly reasonable amount of time without much ado.
Be safe, be smart, be prepared, don't panic.

Super scary cuz you were fiddling around with the gas pedal instead of stomping on the brake pedal. You panicked and reacted improperly. If it ever happens again - just hit the brakes with authority. Your car will stop.

I read on another forum where a guy test drove a lexus is250 and tried to stop the car with brakes at 80 mph (he wanted to see if the brakes can stop a car stuck at wot). It worked the decently the first time, but the brakes fade after that, and does not work so well the 2nd time, and by 3rd, the brakes are sort of gone.

First- the car won't get stuck at WOT if you use the right floormats.
Second- If you throw it in neutral then what the gas is doing is irrelevant
Third- even if you're not bright enough to throw it in neutral you'd have to be a magical kind of dumb to stop the car from an uncontrolled WOT once, and then immediately start driving again requiring a second or third such stop.
no, because our cars are 100% made in JAPAN, where quality control of the building process is refined and doesnt used shitty us/canadian parts like the toyota's affected which lead to the problems...
I dont see how a factory floor mat could roll its way under the gas pedal and if it did, you would notice it. Im pretty sure the folks who originally got their floor mats stuck were just too LAZY to fix their cheap aftermarket floor mat from rolling up. Laziness equals stupidity and unfortunately they end up taking everyone with them and now I cant order the all weather mats.
Stuck gas pedal, just apply brake firmly pull to the side and shut down engine. How hard can that be? Too many dumb drivers around, its upsetting!

First of all, this acceleraor pedal issue is that last thing you need to worry about...
The problems that are arising with Toyota/Lexus are not related to sticky pedals and floor mats, they are much more complex problems related to ECU's. The ECU's are programmed with complex Adaptive Algorithms that determine things like Air/Fuel mixture, Traction Control, shift points, etc... in another words, the ECU "learns" a specific driving pattern, and then "adapts" or adjusts to those settings and tries to create a condition within range. What I believe is happening, is...the ECU is not adjusting on time. This is known as CPU Latency...the time it takes for input/ouput data to reach the ECU and be calculated and then be performed mechanically. We are now seeing this in the Prius and HS250 with their braking system not responding on time. Notice how no other manufacturer is experiencing this problem? BMW has an even more advanced setup with even more complex Algorithms, yet...their engineers know how to make it all work through rigorous testing. Toyota is very very new to this, and they do not have the experience needed/required to develop a proper setup of this kind (my opinion). That is why everyone started saying, "what happened to Toyota's quality?" back in 2003 when drive-by-wire and other electronics made their debut in Toyota and Lexus cars. Go read about 4Runners accelerating on their own at a stop light, a very common problem that Toyota has ignored since 2003. This is a SUV that has been known for its legendary bullet-proof reliability and engineering. Wait until they start recalling MAF on all Lexus models soon for improper readings...leading to rough idles and vibrations. Too bad soo sad...well, I only have a few grand left on my loan, after this...Im getting a Bimmer. Their quality has improved dramatically. Not to mention every car maker on the planet now is watching their step.
So to answer your question... "be worried, be very worried!" Although, Lexus customer service is hands down, the BEST in the industry...but customer service doesn't fix poor engineering...its only sprays cologne on it to cover it up.

Wow... That's a whole lotta BS to fit into such a compact post.
The entire first section belies a gross ignorance of how computers even work...and the rest is baseless speculation with zero evidence behind it.
First- the Lexus cars aren't even involved in the gas pedal recall in the first place. The only recall related to acceleration is to address aftermarket floormats getting stuck. Use the correct floormats and there's zero issue at all.
Second...that's not known as cpu latency. I don't think you've any idea the sort of speeds computers operate at. The ABS system alone is taking readings something like 100 times per second
The learning element of the ECU happens over dozens and dozens of miles and has, and could not have, any conceivable relation to any "sudden" problem at all.
What you're saying makes no logical sense at all.
When the ECU is learning it is adjusting things like fuel trims in extremely small increments, and again it's doing this all the time, not just in the couple seconds you hit the gas where it needs to "adjust its learning" instantly.
and when you write

Data travels in the CPU reasonably close to the speed of light (though not quite there). A modern CPU performs millions of instructions per second
I found another post of yours from a few months back, where you had another crazy excuse for the problems... in that one you insisted

So in November you told every it was the servo motors...now it's "cpu latency"? A term you don't even seem to understand? Are you just randomly making up problems every couple months with no evidence for them?
No...the only problem with Lexus cars was when someone put in aftermarket floormats. That's explicitly what caused the one ES350 crash that got all that press, and it's the only acceleration recall for any lexus vehicle.
The issue with the Prius brakes has nothing to do with "CPU latency" either it has to do with an overly sensitive ABS system... in other words the CPU is reacting too quickly. The fix they're implementing is to make it less sensitive.

The sensation is triggered by a 0.2-to 0.3-second lag when the vehicle shifts between its regenerative braking system to the standard hydraulic system, said Marc Stuyver, Toyota Canada's advanced technology and powertrain manager.
The regenerative braking system is used at low speeds to both slow the vehicle and capture the energy created in the braking process to recharge the vehicle's batteries, Mr. Stuyver said.
The problem arises when the vehicle's anti-lock braking system causes the tire to slip slightly after a bump triggering the hydraulic system, he added.
"You will feel a change in the rate of deceleration, which in engineering terms we call a jerk," Mr. Stuyver said. "At no point are you not braking."
To fix the issue, Toyota will implement a software fix on the recalled vehicles that will decrease the sensitivity of the system which causes the hydraulic system to kick in and should eliminate the issue without compromising safety
You then go on to say BMW doesn't have this problem... how many hybrids does BMW have on the road again? Didn't they just introduce their first one 2 months ago? So we've no idea what kinda fun problems BMW will have with theirs. (that one costs about $90,000 by the way, so have fun with that).
