We’ve already seen a straight DQ for a rider who through a bottle to some kids who wanted a souvenir.
It’s either UCI being inconsistent or he threw it in the litter zone 10k from the finish, but I’m pretty sure it was closer to the finish than that. Might be wrong.
What's the penalty though? Let me guess - up to the commis?
Also, it could be argued that a wayward rain jacket is a danger and therefore it was in the interests of rider safety that it was thrown away.
