Ah yes it was careless. The site I read the story on initially, stated it was 'dangerous' but I've looked elsewhere and it seems the guy did admit to the lesser charge after simply 'not seeing the motorcyclist'. This possibly warranted the conviction of careless because a witness behind the car did see the motorcyclist from further away. If the driver saw the rider but believed he had enough time to cross based on the premise that he assumed the cyclist was in the speed limit; charges against him may have been dropped. Still harsh to be convicted in such circumstances as the bike was solely the aggravating factor.
