Mac has given a car to Lewis that suits him down to the ground .
They've done a great job for Lewis in that respect .
But , on the other side of the garage , Button has struggled all year long .
When Lewis lost it and tweeted telemetry , it showed he wasn't expecting to have lost to his team-mate .
He knows the car suits him and doesn't suit Jensen .
His comments that had him discounting next year as a write-off seem to point not to the fact Button can't drive around a good car's problems , but rather that it's only a good car for Lewis , himself .
