My heart goes out to this family. If this is the right accident,(happened about 2nd week of Sept) this man was behind me coming up fast to pass me in the fast lane. There was a motorcycle with a passenger directly in back of me. This man (in a silver sedan) sounded like he hit the cement highway divider, I heard a pop like a tire blow out and in 3 seconds I watched this accident happen in my rear view mirrors. He just missed the end of my car as the motorcyclist slowed down and he veered between us crossing over 3 lanes with out hitting anyone else and crashed head-on into the cement retaining wall. Everyone who was going with the flow of traffic on the highway had all slowed down to about 40 as I know we ALL heard the awful crash and saw it in my right rear view mirror. I was in the third lane, I would of stopped but I saw 2 other cars pull over immediately for help.
I was shaken up for days and tried to find out who this was. My sincere condolences to the family and loved ones of this man. I hope this info helps out in some way.
