Natural rights. Behaviours which can be universally shared between all individuals. For example: Murder, theft, assault, and rape are all examples of property violations which we can not prefer for ourselves.

You do have a right to protect yourself, if that drunken driver was gunning straight for you then yes you can make a case for either yourself or another individual to shoot the driver in defense. However you made no claims of where the driver was heading, just that he was drunk. It doesn't matter whether there's a man in a blue costume or not, do YOU in that scenario have the right to shoot/stop the driver, and can you make a case for your defense upon doing so.
