Accidents tend to happen because there's no time to react, or because someone makes a mistake. Either way, once things are in motion, that's that. You can't pause an accident if you're in the middle of one.

But if you could pause an accident as it was happening, like in this anti-speeding ad by NZTransportAgency? Things might get rather somber.

Damn.
