WOW! that's fast - about ayear ago I was driving at nite with the top down, tunes blaring when I noticed headlights quickly coming up from behind, pulled over (was doing 85) and a 911 flew bye, WELL - did about 130-140 to catch him, we played for about 45 mintutes - while it was a blast - I still had the top down running over 120 - and finally reality took over - blinked my lights to him and came back to earth at 85. The 911 vanished!
That was the fastest 60 miles I had ever gone! at 170+ - not sure I would want to know!
