When the fans have a favorite, and he was close, and the flagman has to make
an unpopular close call, he becomes the worst guy at the track. When the flagger
is watching a line across the track, and he is watching 3 mowers cross the line at
one time, he has to line of sight it, and split second that call right then. Most of
the fans are looking at the finish line at an angle, and the call has to be made in
the flag stand. The only way you can take that call out of the flaggers hand, is to
have a high speed mounted camera at the line.
