VT MAVERVICK--- Bingo, you're a winner!!! That is the exact problem. The gas pedal and brake pedal on the VX are closer together than found on other cars. It's extremely easy to depress both pedals (gas & brake) at the same time if your not paying attention.
It happened to me only once to teach me a quick lesson. When I first got my VX from eBay and got in it for the very first time at the D.A.S. shipping terminal, I depressed what I thought was only the middle (brake) pedal, but my big foot also caught the edge of the gas pedal at the same time. The engine RPM's immediately raced up and the VX lerched forward (thankfully I was in an empty parking lot). It scared the ba-jesus out of me!!! I got out and examined the layout of the pedals and found them closer together than on other cars.
I've got very big feet and wear a size 12 shoe; so what's the cure??? For me, the cure is whenever I want to depress only the gas, I make a concerted effort to rest my right foot along the extreme edge of the transmission housing thereby missing the brake pedal. Whenever I want to depress only the brake pedal, I lift my right foot and "hover it" over to the extreme left, thereby completely missing the gas pedal. After a while, this "foot placement" practice becomes habit and now I do it even without thinking about it.
In addition, whenever I come to a Red-Light, I keep my foot on the brake and move the transmission lever to Neutral by pushing the lever forward without depressing the detent button. By not depressing the transmission detent button prevents the lever from accidentally going into Reverse (very important). Then when the light turns Green; with my foot still on the brake, I merely slide the lever down into Drive (again, without ever depressing the detent button). Then I move my big right foot over to the extreme right side next to the transmission hump and off I go.
