Like Race Radio pointed out, that was no ordinary bottle. It was one of the stickier bottles I have seen in a long time. I don't mind the current rule, it's only 20 km and the bikes can hold two bottles. Car support would be a nightmare on the climbs and dangerous on the descents. Soigneur support... well it could be difficult to collect them from the feed zones and drop them off in the last 20 km. More bloody cars zipping past the riders. Moto support... that idea has merit but surely riders would be hanging on to sticky bottles or riding in the slipstream under the guise of grabbing a bottle.
What I didn't like was the penalty being applied when the rider grabbed a new bike from the team car. The man needed a bottle. But this can't be the first time that has happened, maybe SL should have used a little foresight. Apart from that incident, they seem to use perfect team tactics!
