Not to rush to anyone's defence here as I know nothing of this but the police - if true - sure get to charges quickly. It is quite odd. Watercooler raises a good point about his experience. In the "agony of collision" - a legal construct - who is to say that coming around a corner driving maybe a bit more than a day speed as you've done it many times before safely and then in front of you are cows lying all over and you panic and swerve past one and glance off that one and so on.
I 'd not rush to judgment on the media coverage of an event like this.
In context vehicle crashes are serious health and economic issues.
3,500 or in excess of 1 million people are killed every day according to stats offered by the Global Road Safety Partnership. http://www.grsproadsafety.org/
That's about 10 jumbo jets with 350 crew and passengers dying per day across the world and this region is one of the worst for deaths and injury rates.
While if 10 passenger jets went down per day the media would be all over it but we get de-sensitized to it and it doesn't register until it affects us.
