How many times in your life have you been cut off while driving? In how many of those situations did the person who cut you off then stop, get out of their car, and charge you?

I think that waving a gun around is much more likely to get you arrested for road rage than anything else. The other guy might get charged with reckless driving, but certainly not "assault with a deadly weapon."

There are people who do this on purpose -- they load their entire family into the car, swerve in front of you and slam on the breaks, you rear end them. Minor damage, and then they sue you for medical bills plus pain and suffering and lost income. Illegal? Yes. Immoral? Yes. Insurance fraud? Most definitely. Assault with a deadly weapon? No.
