Driving at night down narrow streets, I've had some people pop out from behind a wall in front of me. Fortunately everyone involved has always had good reaction times, so I don't think I've killed anybody yet. Somebody who's not really thinking, or just stumbling around and being goofy. Lots of people including myself have said "DUDE wouldn't it be funny if we did [X incredibly stupid thing]?" while unreasonably drunk. Normally calm people start fights with people who can clearly kick their ass after a couple drinks. Probably a few think they can take on or play chicken with a car. Some people also just blink for a second and suddenly they're asleep, if they have enough drinks. Depression may be a cause, but honest accidents and impaired thinking are definitely big reasons.
