I agree with Debbie, it would seem as if the average bike runs the mile faster than our average car speeds.
What we may not figure in however, is that many of the fast bikes also take the long shutdown and most cars use the short shutdown.
Just a guess but would be nice to see the "total run time"
Take 2 bikes that run 200 MPH and use long shutdown and add total time from first bike starting to last bike clearing long shutdown,,,then do the same with 2 cars running 150 MPH and using short shutdown,,,
I do not know the answer, but would guess the total time may be very very close, and would venture to say the cars may clear a few seconds sooner
