Former F1 champion Sebastian Vettel backed former F1 driver and Michael Schumacher's son Mick Schumacher to join the Cadillac F1 team. "Mick is now in a completely different stage. He is much more mature. And I think he's doing a very good job at Alpine in the World Endurance Championship," he added. Cadillac is set to join F1 in 2026.
