No matter how interesting the new cars are, Formula 1 is of no significance compared to the horror of war breaking out in Ukraine. But, what it can do, hopefully, is provide the escapism of sport – even during testing. New designs, new drivers, new rules returning to an old problem – there has been plenty to dig into over the three days of running at the Circuit de Barcelona-Catalunya. As ever, the usual caveats of testing apply, as all the teams and drivers are keen to point out at every available opportunity. Everyone is somewhere and everyone is nowhere.
