The proudest dads in Australia were in the Toro Rosso garage on Saturday.
52-year-old Carlos Sainz, a world rally legend, was arguably proudest, after his son and namesake out-qualified the sister car on debut.
But he was also arguably the most nervous.
“When you drive yourself,” he told German television RTL, “you have everything under control. Here I can only watch.
“I prefer when I’m driving myself,” Sainz snr added.
Also in the Albert Park garage this weekend is Jos Verstappen, whose personal best laptime around the Melbourne layout has already been bettered by his high-profile 17-year-old son Max.
The Dutch former Arrows and Minardi driver said: “We are very satisfied. He is completely relaxed.
“Of course it is his first race, but he is calm,” added Verstappen, 43.
“We discuss everything together, but I need to give him a bit of space, which is new for me. It’s not a problem,” he added. (GMM)
