As someone with a concealed carry license, I am familiar with the “use of deadly force laws” in my state where I carry.
A car can at times be considered a deadly force weapon.
Generally, to legally use deadly force, I have to feel that my life or safety is in severe danger or that of someone else. Sometimes deadly force can be used to stop a felony.
Driving a car into a porch pirate does not fit any “use of deadly force” laws I am aware of.
Washington Law has a good series of YouTube podcasts on various concealed carry topics. A recent one is on what a person can do if in a car and it is surrounded by a mob. The short version is allow your car to be significantly damaged and if you can slowly move through the crowd without injuring anyone get the hell out of there, otherwise you can’t do much of anything until they are breaking your windows with an intent to seriously harm you.

UNLESS!!! It was an assault SUV. Her only hope of acquittal is if it was a self-driving Tesla.
