Yeah, along with our castle doctrine law (776.013):

(2) A person is presumed to have held a reasonable fear of imminent peril of death or great bodily harm to himself or herself or another when using or threatening to use defensive force that is intended or likely to cause death or great bodily harm to another if: (a) The person against whom the defensive force was used or threatened was in the process of unlawfully and forcefully entering, or had unlawfully and forcibly entered, a dwelling, residence, or occupied vehicle, or if that person had removed or was attempting to remove another against that person’s will from the dwelling, residence, or occupied vehicle; and (b) The person who uses or threatens to use defensive force knew or had reason to believe that an unlawful and forcible entry or unlawful and forcible act was occurring or had occurred.

That already basically means people surrounding and banging on your car, trying all the door handles to enter it, etc. means you can use lethal force. The problem here is that it is still up to the discretion of the DA or SA to determine and you could still end up with a costly legal defense on your hands, especially in the cucked parts of Florida where they have activist DAs. DeSantis' law provides a blanket of immunity in such a case, at least for the case of a being in a vehicle, where even a DA or SA cannot choose to convene a grand jury and try to indict you based on their judgement.
