50 laps? WTF? You want to check your math mate. McLaren could have run a two stop race. That's three stints. So that works out a one 18 lap stint on the options and two 25 lap stints on the primes. Besides, Bridgestone told McLaren that Hamilton shouldn't run more than 18 laps on the options because he risked a failure. That mean't that Hamilton could have used the softs for anywhere between 1 and 18 laps depending on the strategy they wanted. In the end they chose three stops, which turned out to be the right call. So Hamilton's claim that Bridgestone made him do a three stopper was rubbish. Two stops was entirely feasible, though ultimately not as quick. As to your other point, why the hell should Bridgestone make a tyre to suit 1 driver in 20? Who cares if that's 50% of the McLaren team when it's only 5% of the entire grid? Hamilton is the one who needs to change here, not Bridgestone.
