I was driving home from DC when a 911 turbo porsche pulled up next to me and wanted to race. I decided to try, even if he would beat me. I was going around 80mph when we hit it and i only went down to 3rd gear, he pulled on me about a car and a half and then i started to catch back up. I was able to get as close as a car behind him at about 165 or so. He was amazed that i was able to keep up with him, i was amazed that i was able to stay that close to him too. This was at 3:30 am, so there was no one on the road.
