First two races down.
As for the latest "new era" of the sport, I think the on screen graphics are generally very poor. I use the on board/interactive features, which are less in number than last year and of poorer quality. In the car, the halo gimmick lessens the challenge, and obscures the driver's vision for the start lights and the pit lane lights. Indeed the most notable incidents of the races so far have come in the pit lane, and a serious injury. Halo was allegedly designed to reduce accidents, not contribute to them. Ecclestone has already turned up in the paddock to voice his disapproval at the changes made.
China is the next race, the first major challenging track of the season, with the first corner and the hairpin at the end of the long back straight, sure to provide plenty of overtaking opportunities. Hamilton is the favourite to win of course, but he needs to, or Vettel could open up a big lead before the circus moves back to Europe.
