Not all stories have to be overtly sensational or outstanding to be newsworthy. It seems there were a substantial amount of people that cared about this cat in the community it resided in. It's a local story. If it doesn't hold any meaning to you, that's fine. Don't question it's newsworthiness. The thing you should take away from this is that driverless cars are dangerous and we should ALL question if they should be allowed to be used anywhere.
