First of all, the rule should be, don't draw your gun unless you are willing to use it, not that you intend to use it. Most of the time it is not necessary to actually fire a gun to end the threat. I would not reccommed shooting someone unless absolutely necessary.
Next if someone has just tried to kill you with their car, and is either much larger or younger etc., you have the right in most places to prepare to defend yourself.
Also it makes a lot of difference in what part of the country you live. My Father caught a guy (he was a friend of my Nephew) stealing his heart medication and chased after him with a .45. Daddy shot out his tires and then called the sheriff. The deputies caught him and took him to jail. This was in rural Florida and the deputy simply told Daddy it would be a good idea next time to just call them instead of shooting out his tires. I suspect that would have been viewed dirrently in most Northeastern States.

Here in Oklahoma we had a similar situation in a rural area where a father & son (both licensed conceal carry) came to the Dad's home in the process of it being burgularized. The burglars fled in a vehicle and Dad and Son proceeded to chase them down country roads. The Dad leaned out of the car like in a western and managed to shoot one of the burglars.
The father was charged with assault with a deadly weapon - and rightfully so. Here you cannot used deadly force to protect property and you definitely cannot engage in a car chase with gunplay. Only the police can do that stichk!
I suspect that your rural Florida person got off because a sheriff (and local DA) didn't want to press charges. In almost all cases, concealed carry permits are only to be used for the purpose of self defense. Chasing a thief is not self defense.
In fact, here it is not called a "concealed carry" permit. It is referred to as a Self Defense Act(SDA) permit; a reference to the title of the law that created the licensing. There are extremely limited circumstances where you can use the weapon.
Here, if you do not draw the weapon with the intent to shoot, then you did not have a valid reason to draw the weapon; you can be charge with assault. You can't use the weapon for any other reason than your own (or immediate families) protection. You can't even legally come to someone's aid using your concealed weapon, except for an employer(or immediate family as mentioned). The law was written to discourage vigilantes and self appointed law enforcers.
