I'm not surprised, I've seen plenty of young riders dart through intersections like they're indestructible. Last week I saw some guy steal the right of way in a 4 way intersection with stop signs. He made some imitation cop sound as he shot through there, he seemingly did that to alert cars that a bike is going to jump into the intersection
he was lucky that car had not started to move since the intersection had cleared a second before, but not everyone waits for it to clear before they go. He was to the right of a van so I doubt he could even see the opposing traffic
