Well, there's not much information in the story, but either something went very hay-wire, or else this guy tried to take-off on a highway without proper assistance from law enforcement to block off the road. From the picture, it also appears that he departed "the wrong way", i.e. against the flow of traffic, greatly increasing the likelihood of encountering a car.
In any case, without knowing the full story, it's hard to identify who, but it seems clear that somebody stupid was involved here.
