A fallout likely? Definately.
Both Mclaren and Hamilton are constantly testing each other.
2007: The team pressured Hamilton unnecsesarily with the espionage thing. The team were telling him to give Fernando the advantage in Monaco and Hungary.
2008: Nothing stands out in my memory but I imagine had the final pitstop cost him in Brazil there would have been a meltdown!
2009: The team told him to lie, he agreed to lie, both parties were guilty here and they were visibly annoyed with each other. Constant digs at the car – ‘frickin boat’ was used in Turkey (?) – tension betwee the team perhaps?
2010: Button beat Lewis in the beginning and there was visible pressure on Hamilton to respond. Lewis felt let down by the team for the pit call and was furious with woever called him in for an extra stop in Malaysia(?) or Australia(?). Canada he was raging when Button was allowed to catch up. Monza, the team were angry when Lewis chose to go down the non F duct route instead of following their advice. It is also at Monza that (alledgedly) a team member sent an offensive text message about Lewis which he was obviously not pleased with.
However both parties always overcome their adversities and succeed. These confrontations are the result of two passionate parties with a determination to succeed clashing, both want to better themselves.
There is no real need for Mclaren and Lewis to change the way they go about their business:
I’m sure the partnership will continue for many years,
