Anyone else have this issue?

2005 F250SD Ext cab, regular pedals (not the power adjust ones).

I had a scare one time a few weeks back with my new (used) truck. I was backing into a gas pump and the engine started to rev while I had my foot on the brake. Scared the crap out of me but I managed to brake it enough to park it. I realized after that that it was me. I had my foot on the brake but because I was looking over my left shoulder I was inadvertantly pressing the accel at the same time as my right foot rolled over to the right due to my body position. Thinking this through and trying my other vehicles I see that this is not a problem with most cars. It seems the position of the gas-brake pedals caused the surprise. What I noticed is that when you press on the brake a bit until it engages, the brake pedal matcehs up its height with the gas pedal height on this truck, which it does not seem to do in most cars (that I own, or have driven). Well, I vowed to pay more attention, but then it happened to me again. I knew what was happening, but it seems to be too easy to do this. So...Anyone else see this, and more imnportantly how do I change this so I don't have the...Ummm "Audi" Unintended experience in my Superduty.

Thanks for any input given.
