Car Accelerates On Its Own problems of the 2008 Nissan Sentra

I was stopped at a redlight behind about 3 other cards. When the light changed to green I began to remove my foot from the brake when the car suddenly jolted forward at a high speed. I had the brake pedal to the floor but the car did not stop. I maneuvered myself all over the road to avoid pedestrians and oncoming traffic at the intersection. I was able to avoid one head-on collision that only damaged the mirrors as we passed by each other. I went onto the sidewalk taking out several feet of cyclone fence. The fence post nearly punctured the front windshield (lucky) and damaged the hood and other parts of the vehicle as it bounced off. The car came to a stop as quickly as it began. The Nissan "engineer" could find no cause the unintended acceleration. I travel this road everyday. This never happened before. I was not charged by the police who said," I can't believe you pulled this off". I sent a complaint to Nissan and to consumer products safety but I did not hear about fhsa until Toyota began having the same problem. If there was a problem with the car, Nissan denied it. Based on an interview with an electronics engineer that I heard on npr, isn't is possible these accelerations are extraneous? this person claims cells phones and other electronic devices can cause this. I was less than 1 mile from a verizon cellphone tower. Who knows? maybe he is right and the location of the initial unintended acceleration may be work investigating.
