I was in the process of merging onto the Ohio turnpike and depressed the gas pedal to accelerate and pass a slow-moving semi in front of me. The car accelerated and once past the semi I released pressure on the gas pedal only to have the car continue to accelerate. Despite pressing the brake the vehicle did not slow. As I prepared to shift into neutral gear I reached down and pulled the floor mat to the diagonal corner opposite the gas pedal. With that action the pedal appeared to become responsive to pressure and the car decelerated. A rear seat passenger observed a warning light appear on the instrument panel indicating a master system warning. The light disappeared as soon as the vehicle began to slow. No other actions occurred following the incident.

I accelerated to make a lane change, vehicle took off to increasing acceleration I attempted to brake car would not respond. Luckily no traffic was ahead of me. Finally car managed to stop. I didn't think it would. I had to practically stand on brake pedal. I was assuming some how the cruise control was inadvertently pressed but no it was not.
