I don't see that the car driver should be expected and able to allow for a bike closing at 50 yds per second. It is outside normal road experience. Even if he did see the bike nearly 1/4 mile away he would have thought that he'd plenty of time to turn right across that road. He had about 4 secs.
Go on, count it out and do a right turn...No, I put the fault 100% on the bike.
