I completely agree that they would want to discourage it but kicking him out of the Tour is big. After I posted here I went over to TourdeTwitter to see what the riders are saying. This is Mick Rogers' post:
mickrogers Another stage done. Some fireworks in the final km's. I think it's a bit over the top to send @markrenshaw1 home! Warning & fine is enough!
Yeah, I wonder if it might be a cultural thing? Evidently, the tactic is fully allowed in track sprinting. I wonder also since Julian Dean was so sanguine about the whole thing that he might be expected to protest on behalf of Crenshaw the judges' expulsion decision, even though
expulsions for the move are not unheard of in road cycling.
