I've no idea about the US, but I do know that here in Germany, inattentive right turns is a major reason that cars run over people.
Left turns risk crashing into another car. But even if 61% of car crashes at intersections occur then, I have reservations about replacing one opportunity to crash into a car with three extra opportunities to run over people. And particularly if the research doesn't even describe that tradeoff.
