Perez would go off turn nine, turn 10 and he didn’t get a penalty.”Hamilton claims the Silver Arrows have now looked into the 'fundamental changes' that he had been asking for. The Briton believes that the team has made progress in terms of developing their car concept, according to his suggestions for the future.Austria's Red Bull Ring did not suit the Mercedes W14, which suffered from all possible driving issues. Hamilton reported a brake issue, along with massive oversteer and understeer.Speaking to the on-site media in Austria, the Briton said:“Ultimately, there are fundamental changes that have to change for next year. And I’ve been asking for it for over a year. So, I expect to have that in future, which I think will definitely help. But it’s not only that, it’s the rear end, and how it rotates through a corner. But we’re working on that, and the team are very, very focused on that."With Lewis Hamilton's team set to bring major upgrades to the upcoming British GP, it will be interesting to watch the Briton take on his home track.
