Samsma,
Should your lead footed husband get stopped on the way to the cruise ship, there are alternatives to the license being held as bail. Ask to post a cash bond. You will be asked to put up cash, to insure his appearence in court (make sure he shows up, or you will lose the money and an arrest warrant may be issued).
You might also ask if there is a "forfeiture bond" available. This allows you to post bond, and use the bond to pay your fine, without showing for court. You normally can plead guilty by mail. This isn't available everywhere, so you might ask.
Lastly, the best way to avoid this is a rolled up newspaper. Whenever the speed exceeds the limit, WHACK!!!!
