I'm not sure where I saw it but I think I read that most recent increases in Japanese bicycle accidents are from bicycles turning right. It seems like the push to make bicycles use the road more (to reduce pedestrian vs bicycle accidents, which are still rising) had the unintentional consequence of making cyclists more likely to perform right turns like cars and motorcycles. However the road law actually requires bicycles to do two-stage turns, which they were more likely to do when they were riding on the sidewalk, and what cyclists in Amsterdam and Copenhagen recommend doing. So, I mean, sure, more cycling paths would improve the situation by making cyclists perform 2 stage turns, but there's nothing really stopping us from doing it now.
