One year ago, driving from Wash DC to Baltimore to pick up my son at college, I got to the Baltimore beltway (huge road circling general area).
It was cold and 'slightly' icy-wet. I was tooling along in relatively moderate traffic at maybe 55 MPH in center lane. Suddenly a movement to my left and slightly ahead of me in far left lane....and this kid goes swerving and spinning IN FRONT of me towards the right! He missed me by about 20 ft. and spun about 4 times, ending facing backwards in far breakdown lane. He never hit a thing....

After picking up my son, we headed back, and that car was still there, surrounded by 3-4 police cars. I never did learn what happened to him...his car looked uninjured...but who knows....
