Speed Control Cable problems of the 2005 Honda CR-V

I had just come off the highway and turned onto a state road. I was slowing down for the upcoming intersection, when suddenly the car started speeding out of control and the brakes could not stop my car from slamming into the car in front of me. After the crash, the woman I hit pulled over to the side of the road. I put the car in drive with my foot on the brake and the car revved wildly. This was later noted by the woman I hit, as well. In desperation I turned the key off and let the car roll to the side of the road. The firemen disconnected the battery for safety. When the tow truck driver came, he reconnected the battery cables and the car started itself up and began to rev. The driver said he had never seen anything like it before. I have his name and number. The airbag never deployed and I was fortunate to only receive whiplash and my dog seems ok. The other driver has back problems but was fortunately driving a Nissan xterra that did not get nearly the damage my car received. I am just so thankful that my children were not in the car, and that there were no pedestrians or children in front of me.
