Free Practice Friday at Silverstone was free of too much drama, and it was Valtteri Bottas who was fastest in both morning and afternoon sessions. Sebastian Vettel had other things on his mind, , as he and the Ferrari team tested out the new shield cockpit protection prototype. He only had the windshield style device on his car for a few minutes, however, before stopping the test early because it made him feel dizzy. He said: “I think it’s because of the curvature, you get quite a bit of distortion.”
