i don’t know why i bother.
If there was just small debris, maybe a piece hit a pedestrian. He wouldn’t know if immediately flees the scene.
It was reported as “witnesses removed large debris” from the road.
Nothing is large on a scooter. It’s likely they removed it. But you know what, there’s no point discussing it with you because you “know” what he “wasn’t” arrested for without apparently knowing the law.
The police were called, responded, and saw enough evidence to track them down and issue him a summons, he’s lucky he wasn’t charged with more after admitting he was racing.
