	To make this work:

1.  You'd have to convince a court of the validity of Roll's Theorem,
    which might be hard.
2.  You'd have to print the "do not exit before this time" time on the
    ticket.

	Also, speed limits aren't like that; usually the limits are
set at the 75th percentile or so of speed, so the police have a reason
to stop anybody driving unsafely fast.  Most of the time, a 55 posted
limit means traffic flows between 60 and 65.  A 65 limit means it
flows between 65 and 75.  If they went around busting people for
driving 60, they'd run out of goodwill real quick.
