Grow up.
Of course I would stop to stop a truck dragging your ass down the street, and not worried about "Bubba" returning fire from a moving truck. I just came back from my 2nd consecutive day at The Range, and am better than Bubba in a rolling pickup, probably why the range operator watching me shoot was trying to get me into the next competitive combat shoot there.
Florida? Big deal. Florida law is pretty clear. If somebody come at you with shears, you can pull you weapon and if they don't stop, you will probably be on firm ground to shoot them until they are no long a threat, as you are in fear for your life. I have been carrying a weapon legally in Florida for years, every time I go. They honor my permit, as well as the permit of Chief and his wife the Colonel, that often comes with us, as they carry, also, though we have never had need to pull a weapon down there, or in transit to and from.
Yes, if you cannot handle yourself or the situations you allow to escalate around you, by all means, learn to handle weapons and get a permit and carry, as is your right. I say get a permit, as there are plenty of "Bubbas" out there with no clue, and a danger to themselves and the public. I advise you to take the training seriously (as your life may depend on it), keep a card from your lawyer in your wallet right behind your permit (I do) and join an organization of your choice with insurance and legal services provided, realizing, if you shoot, you are probably going to be arrested, even if you do not stay long.
