He robbed a bank. :)
Really, no reason to get into the whole Vettel x Alonso debate. Time will tell, that’s all.
And even when Vettel makes mistakes, he makes up for them. He makes mistakes, sure, because he risks a lot when he needs to; and he might just get better. But Alonso was not as strong in the 2nd half of the season last year as he was in the first, I think no one really doubts that.
Well anyway, I said enough of the Vettel x Alonso debate and there I go again. By the way, Alonso is the most complete driver on the grid, I reckon; but the gap to Vettel and Hamilton is smaller than he thinks, and some other people think. And time might still change the whole perception.
