Discription of Events: I had my cruise set at 70 mph -the speed limit- and was passing a car. This volvo came up from behind so fast I thought it was going to hit me. It slowed at the last second. When I finished passing I moved back into the slow lane and the car flew past only to take the next exit where I was going and I ended up following the car through several lights. At each light the Volvo took off aggressively only to have to stop again at the next light with me coming up behind her
