I'm not sure why there is a huge debate over if the problem exists or not. It definitely does exist. It is a simple problem to fix with some simple pedal re-alignment. Last week I flew to a conference and got a rental car. It was a brand new Hyundia Elantra. I purposely tried to get my foot to press both pedals at the same time and could not do it. The pedals are placed in a way (as in most cars) that you cannot clip the accelerator with the right side of your shoe while pressing the brake... and this is a sub $20K car.
Yes, Tesla can keep trying to fix a hardware problem by tweaking the software. But why not just re-adjust the pedals properly and fix it once and for all?
Because as others have said, it's not a problem in the first place. The driver of a $20,000 Hyundai Elantra is not a performance enthusiast and the car is not designed with pedal placement like what you find in performance cars. Perhaps you can ask Tesla, after they move your pedals, to also hobble your car's performance to better match that of the Hyundai Elantra. After all, that's what the Elantra's pedal placement was designed for.
Just because you are having an issue with pedal placement doesn't mean there is a "hardware problem". In fact, maybe Tesla should just make the Model S into an Elantra because then you literally don't have to think about anything. All the controls are where you expect them, the doors open how you expect, the seats work how you want... so there you go. There is always a learning curve and adjustment that takes place when you acquire a new vehicle. LEARN ABOUT YOUR CAR! If your pedals are closer than in your Hyundai Elantra, then take extra care and pay attention. Just because something is different does not make it wrong. It just means that you have to learn a new way, much in the same way that you've already learned a new way to drive this car, eschew knobs for touch screen controls, etc. You've adjusted to other things, yet none of those other things were "hardware problems".
My last car was a Prius and probably had widely spaced brake and accelerator pedal. I had absolutely no trouble adjusting to the Model S, none whatsoever. In fact, I am in awe of the pedal placement because it allows me to pivot my foot on my heal to either touch the brake or go pedal. I couldn't do that in my Prius and that car always caused me leg strain because I had to move my whole leg to switch from brake to accelerator. Model S design is superior by far.
