When a tyre or car bounces off the catch fencing you're standing behind, you'll be thankful it's there. Drivers in a top team are expected to perform at a top level though. Giovinazzi and Kubica are performing badly compared to their team mates, but because they're in a bad car it isn't that much of an issue as it is at the top. Gasly had time in a Toro Rosso to get up to speed with F1 and was supposed to be quick or at least consistent in the second Red Bull. Gasly was lapped by Verstappen twice on pure pace when he was battling for the lead. You should never be lapped by your team mate especially if you aren't involved in accidents or screwed over by something out of your control (other blue flags, pitstop mistakes). No, Gasly has botched his chance, has hit a wall too many times and was damaging the Red Bull brand. Verstappen might be driving out of his skin at the moment, but even Massa in 2012 and 13 when he had outstayed his welcome in a top team was able to keep the Ferrari near the pointy end of the grid most weeks. Gasly has been mired in the midfield too often and is not picking up the points that car should be picking up. If he had performed in Germany and Hungary like he did at Silverstone, he would still have the seat. But a crash in practice, a lockup at the T6 hairpin dropping him to last, followed by a crash with Albon in Germany and a dismal Hungarian Grand Prix where he only got ahead of 2 cars because Red Bull are great at pitstops and an anonymous pursuit of Sainz later and it was curtains. Interestingly, Gasly is leading Reddit's "Destructors Championship" which tries to quantify the amount of damage each driver has accumulated through the year through crashes, and he has been replaced by Albon, who is second on the list.
