I'm usually one of the first ones to say most accidents can be avoided by making yourself more visible by adjusting lane position and speed/space management but I can't see anything the rider did wrong, maybe riding too fast but I really don't know that. It think this is a rare case where the rider was doing everything he should've been doing.
The car, as far as I could tell, didn't even have a turn signal on, there were no other vehicles around, the bikes were riding staggered.
My guess would be the driver and passenger were talking and possibly made a last minute decision to turn. Looks like a kid in the passenger seat, I'm thinking a distracted driver. If you look at the shadows, the bike would be coming straight out of the sun, not an excuse but possibly a contributing factor. Had the driver given any indication (such as a signal) that she wanted to turn maybe the rider could've taken the sun into consideration and adjusted his speed or changed his lane position or covered his brakes, but without any notice, the rider had no reason to suspect a turn was coming.
If the rider had just had a loud horn.
