I've had this happen exactly one time in my 12 years driving so far (about 4 years ago when I was 22) and it didn't end well for them. It definitely wasn't intimidating for me, just made me extremely angry, though it did intimidate them after I beat the shit out of them and then pulled their wallet out, took a picture of it, pulled my gun, showed them both the gun and the picture and said "look! Now we both know where the other one lives!" Then threw them back into their car.

This was also when I was single and couldn't care less if someone tried to break into my place for revenge. Now that I have a fiancée I'd never do shit like that for fear they'd come back with friends lol.
