60km/h is pretty fast, what regular road has that speed limit?
The guy that is turning is at fault, but I can't say the guy driving with the cam was not careless. He changed lanes at the last minute to pass the guy turning in front of him, so the guy that hit him probably saw no one coming and began to turn as the driver with the cam switched lanes and tried to bolt through.
It's an unfortunate event, if the person with the cam slowed down a bit when changing lanes he might have seen the other guy coming.
Not sure, seems a little careless on both parties involved.
