why is it that every goof in a new challenger wants to race me?

Bikes are quick and fast. Never raced one before but one time on the freeway I got to play a little with one. I was in my Dart going to a show. Riding along with me cutting through traffic was this lady on a green bike. She was good I could tell and we would take turns getting through traffic. Then all of a sudden traffic almost stops. So we start cutting through it. Next thing you know we star seeing some kind of hatch back rices then more. As we get up a little farther we are now suronded buy them. We can now see why traffic is so slow. The ricers are taking turns taking up all three lanes and going from a stop and racing each other. So we get up to the front row and they take off. But me and the lady on the bike were ready. One of them got a little ahead of the others and I blew through that hole and past them like they were sitting still. The bike lady was right there with me. So we are going through the gears and I hit 120 and decide that she wins. At that point I am at 5500RPM and looking for another gear that I don't have so I let of. She just keep on going and took off in to the sun set
