I'm really surprised this thread has gone on this long about (what would/should be) a common sense issue. The jogger made a U-Turn without first looking around to make sure it's safe. We actually have signs that say if you are going to turn around, you need to first go onto the shoulder and turn around and look and then go into the other lane. The jogger isn't an idiot but he was certainly in a moment of not thinking. There was nothing else the cyclist could have done about it to alleviate the situation, except for not being there in the first place.

Common sense people, seriously.
