In an upsetting video you really, really shouldn't watch unless you're prepared for it, or interested in the kind of stuff that gets posted, like this did, on violent video site World Star Hip Hop, a man threatening cars with a machete in an Oakland intersection appears to have twice been intentionally run over by separate cars.

The hit-and-run attacks — they do appear to be retaliatory attacks — on the armed man occurred at 37th and International Boulevard at around 3 a.m. according to CBS SF and police.

The raw footage below is lengthy, heavy on expletives, and probably NSFW (with audio on, at least). And the whole incident is totally condemnable.

The Oakland Police Department has not provided the media with information about the incident, and the machete-wielding man's condition is not known at this time.
