Swampman - you defend your position by ignoring the intent of this law and citing extreme exceptions.
Here is what I found on the actual verbiage:
(1) A person who violates the provisions of s. 316.2085(2) or (3) shall be
cited for a moving violation, punishable as provided in chapter 318.
(2) A person who exceeds the speed limit in excess of 50 miles per hour
or more in violation of s. 316.183(2), s. 316.187, or s. 316.189 shall be cited
for a moving violation, punishable as provided in chapter 318.
Section 2. Subsection (2) of section 316.2085, Florida Statutes, is
amended, subsections (3) through (6) of that section are renumbered as
subsections (4) through (7), respectively, and a new subsection (3) is added
to that section, to read:
316.2085 Riding on motorcycles or mopeds.—
(2) A person shall ride upon a motorcycle or moped only while sitting
astride the seat, with both wheels on the ground at all times, facing forward,
and with one leg on each side of the motorcycle or moped. However, it is not
a violation of this subsection if the wheels of a motorcycle or moped lose
contact with the ground briefly due to the condition of the road surface or
other circumstances beyond the control of the operator.
(3) The license tag of a motorcycle or moped must be permanently affixed
horizontally to the ground and may not be adjusted or capable of being
flipped up.
Looks pretty specific to me that the law is addressed towards being permanently affixed and not made to be unreadable. So, before you lift your leg to mount the bike, check that you have a tag. If it is gone, make out a police report. While you are looking for the tag, make sure you have air in both tires as well. Have a safe ride.
