VIENNA: Max Verstappen at the Red Bull Ring is usually a recipe for success. The defending Formula 1 champion has an upgraded car for his team’s home race in Austria — where he’s won five times — on the back of an encouraging second place in Canada, where his two McLaren rivals collided. Zoom out, though, and the situation is much more uncertain. Verstappen remains at risk of a one-race ban for too many penalty points, Red Bull teammate Yuki Tsunoda is usually too far adrift to help him, and Verstappen’s own future is far from clear.
