Coming home yesterday from a twelve day ride. Heading south on I-57 in Illinois. As I'm passing an on-ramp, two cars are accelerating up the ramp. I move over to the left lane. There is a truck in front of the cars in the right lane as they enter the freeway. Apparently not wanting to stay behind the truck, and looking to the left/behind you is so passe, the lead car moves to the left lane, with my from wheel even with his back door. Can you say BRAKES !!! I no more than cleared him and got my shakes under control, when the cell phone wielding idiot in the second car does the same thing. It takes me a couple of miles to stop shaking. I don't think either of them even knew anything had happened. What a horrible way to have ended a ride if I had not been keeping an eye on them.
