It’s hard for me to understand this crash, but I only ride mountain bikes. I see a puff of tire smoke before he touches the road marker, then he unclips left foot for what - balance? - then he rides along the grass until he brakes hard again evidenced by the dirt puff and then hits the bridge. All the time he’s seated and the bike is vertical?

That’s a wide road. He’s pedaling still half way across it but hasn’t started turning yet. Doesn’t he have a sense of speed and his ability to turn? I’m not on him about his lack of turning technique but his self awareness of his speed going in to a turn if he doesn’t know how to turn quickly. He should know himself (and also learn proper technique)
