Were you going downhill? Gravity is 9.8m/s^2, so that's acceleration without pressing a pedal. Otherwise, yes, strange things could happen I suppose, but you have no proof other than your subjective feeling that the car accelerated. Plus first post skepticism and we're at a stand still with this. I don't believe it without further corroboration.

Disruption is hard.
Oh no, I believe him! I had it happen to me, too!
I went about 10 miles before I could stop the car! It was the scariest thing I’ve ever experienced. My wife was traumatized by the random unintended acceleration, and passed out from the sheer terror of the disaster.
Then I woke up.

Yes you absolutely did, the car didn't accelerate on it's own. You committed human error, live with it...

With creep on - the only danger is you may end up creeping unintentionally.
With creep off - you may end up accelerating unintentionally.
have you guys also noticed how all of the SUA incidents ALWAYS happens when the driver is about to come to a full stop in a parking lot? hmm I wonder why?

Hmm. I get unintended acceleration happening fairly regularly. Then I realize TACC is on. I don't always remember that TACC stays on if I terminate autosteer by overriding it using the steering wheel. It can be disconcerting to have the car suddenly speed up for no apparent reason. But pressing on the brake turns off TACC so it doesn't happen over and over.

The same thought crossed my mind. Exactly where a full brake pedal push would be used. Oops.

The truism of technology is that ...''hardware breaks, software has bugs and people make mistakes'. Any and all of these things can occur to cause a system to fail. Blaming all failures on human error is myopic, in my opinion.
Over 10 years ago we ordered a new BMW 3 series which I discovered had an electrically operated steering column lock. The previous design point was to lock the column manually when the key was turned to off and removed. BMW's automated feature would lock the steering when the fob was removed from the holder. My fear was that an electrical malfunction would lock the column while the car was in motion so I asked for this locking device to be removed from our car before delivery. The risk of a problem far outweighed any theft deterrence provided by a locked steering wheel. At the time of delivery all cars including ours had this feature disabled.
You can rate the risk of a problem caused by hardware, software or operator but it never goes to zero for any of them. That's perhaps why I am open-minded to the possibility and why each error needs to be investigated. Pilot error is just too easy to declare even after a plane banks left and plows into the earth.

Until we see an SUA on an open road where the driver did not have a need to stop, there is no reason to go on a software/hardware bug witch hunt.
I stand by what I said. I had to catch myself with the brake because I used the wrong pedal. My habits are wired hard for manual transmission vehicles and I find creep dangerous and unnatural in all vehicles.
Also, I cannot stand the Disagree button. If you have a counterpoint, say it. The button is silly and cheap. (Yes, I have used it. I am not pure here.)
I feel the same way. It propagates the notion that truth is democratic.

(I have described the following events in several threads on this site.)
I have experienced not one, but two sudden unintended acceleration events in my 2015 P85DL.
These two very scary “sudden accelerations ” events occurred in the first year after delivery. Both occurred in parking lots where I was maneuvering at 4-5 mph, and both occurred when suddenly and unexpectedly I hit 6 -8” high curbs located in places where I didn’t anticipate hitting anything. My knee jerk reaction was to hit the brakes, of course. Unfortunately, in those days I kept Creep turned off, so my foot was on the accelerator, not above the brake. So when I “hit the brakes” my foot actually hit the accelerator and power launched right there in the parking garage. Remarkably, I had the same accident on two separate occasions, under identical circumstances!
Thanks to good luck, I didn’t hit anyone or do any property damage, even to the car, although I was really shaken. Thereafter, I spent a lot of time analyzing these two events, and concluded that Creep off was the cause.
I now keep Creep turned on, so that when slowly driving around in a parking garage the natural place for my foot is over the brake. I have had no more “sudden acceleration” scares since then. Now if I hit something in a parking lot, the result will be braking—not acceleration.
Two of my family members, both women over 70 who had never been very good drivers, have also experienced sudden acceleration events, and both swore their feet were on the brake, not the accelerator. I did enough analysis of each crash, and pedal error was the only logical explanation in both cases.
The hard truth is, it basically impossible for a car like a Tesla to accelerate on its own.

Could be regen kicking off for some reason. That happened to me fairly regularly in my Leaf and Volt, where if I was on regen and I went over a slight bump in the road regen would kick off for whatever reason and it felt like the car suddenly jerked forward until regen re-engaged. Dunno, but i will note that it does seem a little odd this is apparently your first and only post ever on this forum.
It does not seem odd to me. Everyone has to start somewhere, and it is a balanced story.
It is still driver error even when it does happen to you, but now you know what it feels like to be sure you didn't make a mistake even when you did.
Tough to deal with that self-doubt when you have years of no errors behind you. The good news is you probably have years of no more errors in front of you as well, just takes time to get comfortable with that thought...
