One of my sisters, in Spain, that was her first race outside of Australia, and that was a good weekend. Now my grandfather the same, so maybe I need to get my family members one by one for the rest of the races. I didn't know. It seemed like the best person to dedicate it to. It's a nice thing to do."In his Instagram post, the eight-time F1 race winner shared a series of pictures from his celebrations, including one with his grandfather in parc ferme.
