Aston Martin performance director Tom McCullough has suggested Sebastian Vettel could have been "more selfish" when venturing on a bizarre detour during the second day of testing.
The four-time F1 champion came to a halt on the outer loop of the Bahrain International Circuit, better known as the host layout for the 2020 Sakhir Grand Prix, after discovering an issue with the AMR22.
The team was able to get the car turned around ahead of the conclusion of the morning session, only after a lengthy wait for it to be returned to the garage.
"He reported a vibration," said McCullough. "We, on the cautious side, just stopped the car to have a good look.
"We got the car back, but it took a while to get the car back, unfortunately. He did the right thing in trying to get out of the way.
"But actually, he could have been a bit more selfish and stopped out on track and if they would have red-flagged it, we would have got the car back, but anyway, we learn from that.
"Got the car back, checked it over and all good."
Nicholas Latifi ended his day early on with flames billowing from the rear of his car, with McCullough citing caution for Vettel's stoppage.
"We have just got to be a bit more cautious, risk and reward at this time," he explained.
"Obviously, we saw the Williams go up in flames so if in doubt, be cautious."
