Meh, people said that about Schumy and yet all those that knew him personally said it wasn't arrogance at all. Maybe it's the same for Lewis.
Or maybe it is arrogance, after a lifetime of your parents raising money just to keep you in karts as a kid, travelling far flung corners of the world (or at least Europe), then maybe you do expect you're better than everyone else.
A Brits a Brit and I like them on the grid, and the podium.
