Brad what did you think when Kovi moved over for Hamilton?
Can't remember the circumstances Nick
If you're on different strategies, I think it's fine to get out of the way and let that situation play out. What I don't think is acceptable is moving over to let someone else win. The moral ambiguity comes if its the last lap of the last race of the season and doing so wins the championship. But that's nowhere near being the case here anyway
At the end of the day, spectators want to watch a race, not a calve up. Some of the great duels have come between rival team mates in the best car of the time. FIA have acted before in the face of Schumacher / Coulthard situations, they should have the courage of their convictiion and retain the key element of contested racing
