Pretty outrageous first of all that they are calling this an "amazing outburst", but that's what the media do. He's simply laying a few facts out there about the things that went wrong or became stagnant with the car's development over the course of the season, in my opinion. But I'm also just going by what I've read, so his manner of doing this could be different than I'm interpreting. Also quite disappointing that he's immediately released an apology so soon.
