Daytona and Le Mans are not really drivers' circuits, IMO. They are cars' circuits. Endurance and F1 are like chalk and cheese. Alonso tried endurance, and came back to F1.
I like to see drivers do different types of motorsport. Whilst the 2 types or racing are very different, Max can show of his ridiculous consistency. Much like Alonso did when he did Le Mans and Daytona
