DMV

This morning I spent over three hours to try to register my vehicles.  It is always a long experience in that place.  I have two vehicles and a jet ski with a trailer. I registered my car a couple months ago, and the DMV input it into the computer wrong.  So since January I have had a license plate on my car under the wrong name but was registered somewhere else under my name.  I actually had three profiles in the FL DMV.  So when I tried to register my SUV red flags went up when I mentioned my car.  I was there forever I got so angry that I could not waste more time to register the jetski and trailer.  I was a little angry on my way to class this morning.  I know it was a mistake, but it makes me wonder how it happened?  What would have happened if I got pulled over?
