Finally... ALL cars manufactured have sufficient brake power to overcome any amount of "go" power you put in with the other pedal. ...
How freaking scary. This represents one of the many concerns I have with respect to my car and the underlying technology. You mention "Tesla", but elaborate with respect to whom at Tesla; just their role. Service manager? Risk management, Support?
My recommendation, maintain a level of professionalism, be tenacious and keep copious notes regarding all interactions with Tesla personal regarding the matter.
Really sorry your car is damaged especially being so new. Is this your first Tesla? You said this happened on the 18th, have you had an estimate yet?[/QUOTEhasbeentowne

It looks like Tesla refused to talk with me now, is there any way to get my message crossed to corporate level?
@Ying - No, you don't have to post any photos, that is not a requirement.
I'm sorry you had an accident. Welcome to the forum. Most of us are friendly.
I was coming to post something similar.
I don't think Tesla would intentionally say that the car didn't accelerate when it in fact did (sure, I remember the AP1 on-ramp to off-ramp, and the 691HP, and the FSD, and all the other broken promises, but this is veeeery different).
Where I wouldn't give 100% faith is that the raw data is being recorded correctly. Do I think it is? Sure do. Am I 100% certain? Hell no.
Important to state the OP joined today, and has exactly 1 message prior to considering his credibility. not saying that it did not happen just that without further proof it's hard to judge.
That's highly unlikely. The driver would have had to have maneuvered to the spot with AP engaged and would have had to have never hit the brake.Could it still be engaged in Autopilot?
It's time to face the facts that you messed up.I agree. I have done my research and expressed I'm willing to work together with Tesla to find out the root cause. Tesla refused to take the car in to take a look. The person I talked to is a service manager from Santa Clara Service Center. I have requested to meet with the engineering team to review the raw data and having an engineering approach to analyze the possibility on things can wrong. I was rejected on this offer.
With the resource as an executive in a public technology company with thousands of EE engineers, I believe a more sensible way to convince me and many more people out there facing the same puzzle is to provide a data breakdown with force input on the pedal and distance the car moved. An electricity footprint on the "log" is a result, not the cause.
Tesla has been approaching 200,000 cars as of today, since they launched in 2012, divided by 52 weeks a year, we are standing on 0.7% possibility cars with SUA problem. In another perspective, there are 1400 Tesla cars out there acting as ticking bomb with SUA issue whenever there is a negative voltage in the control loop.
Are we betting on our odds on the 0.7% or 99.3%? If this issue becomes a public safety issue, we will not and we shall not compromise. A fail-safe design to prevent the current spike in control loop should be enhanced.
The engineering dialogue should be opened with a transparency. The discussion will be 1. Control loop with a map having speed as one input variable 2. voltage compensation operation

You can submit a message via your MyTesla page by selecting "Escalate to Executives" or something like that.
I've been told exactly the same thing by someone who used to run the Tesla autopilot team. We were discussing a similar claim - and he explained to me why it couldn't happen. It's nice to see the same information coming from another source. I'm sorry, @Ying, but I have to agree with Big Earl & others who have suggested you pressed the accelerator, thinking it was the brake.A couple of things.
Two: The accelerator pedal has two potentiometers as a fail-safe. In addition, the two potentiometers read opposite of one another. At rest, one will read 0% and the other will read 100%. At full depression, the first will read 100% and the latter will read 0%. This creates checks and balances between the two and invalidates your suggestion that a voltage fluctuation would cause the erroneous sensor reading, as such a fluctuation would cause an implausible signal code to be stored by the car.

This type of electronic throttle is nothing new to the industry. Volkswagen and others have been using a similar setup for over two decades. I’m personally coming from the Volkswagen side of things and I’m very familiar with the design, operation and troubleshooting of these systems.
I personally believe that you thought you were feathering the brake pedal but your foot was actually on the accelerator. Your foot movement resulted in a sudden application of power instead of the braking that you had expected. It’s an unfortunate, but not uncommon, case of operator error. If you believe differently, your only real course of action is to have a lawyer request the vehicle logs from Tesla.
Final thought: your probabilities and statistics regarding SUA are completely made up. I have seen absolutely no evidence anywhere to support your numbers.
The traction motor on the Model S is a three-phase induction motor instead of a permanent magnet DC motor for the electronic throttle.
