Yuki Tsunoda losing patience with F1 trend: 'It's really pissing me off'

Yuki Tsunoda has expressed his displeasure with the persistent disruptions to second free practice sessions in F1 of late.

The Red Bull driver ended FP2 at the Singapore Grand Prix down in P11 after multiple red flags interrupted the final hour of running on Friday, when low-fuel, soft tyre runs and race simulations are performed.

In total, 22 of the session's 60 minutes were lost.

As the most representative session before qualifying and race on a grand prix weekend, they are more important than the first and third sessions.

It is even more the case at the Marina Bay Street Circuit, as it is the only practice hour run after nightfall in the Southeast Asian city-state.

Almost a second slower than team-mate Max Verstappen, who finished third-fastest, the Japanese driver could not prevent his frustration spilling over during his media duties, saying: "Yeah, it's tough.

"Not being able to have a smooth session, probably [frustrating] for everyone.

"But yeah, it's kind of a trend in FP2 that we're never able to have a clean session. So, it's really pissing me off, but, yeah, it's life, and I think [I just need to] stay calm and, yeah, optimise the setup, and that's it."

Multiple red flags occurred in FP2 at Zandvoort, and Lance Stroll blocked Tsunoda on a quick lap in the following round at Monza. Last time out at Baku, numerous yellow flags also impacted running.

Lap times dropped from FP1 in Singapore, as expected, with the cooler temperatures and track surface continuing to be rubbered in, but Tsunoda did not feel there was much more grip than before sunset.

In contrast to some of his peers, the Red Bull driver found he was struggling with front-end grip in his RB21 during FP2.

"It was not much easier. So, some cars, yes, some cars no," the 25-year-old explained.

"We struggle, at least with front [grip] still. But at least towards the end, it started to get better and better. So at least some positive there."
