The true MVPs of Spa 2021 - The fans at the track who stuck it out. On the whole they seemed to try and keep a party atmosphere going.
From the travelling circus that is F1... MVPs are Martin Brundle and David Croft keeping 4 hours of footage of basically drenched fans and fog actually interesting. Even when reading the rule book trying to work out the options. On the Sky F1 feed they even didn't resort to commercial breaks every 5 minutes.
At least F1 acknowledged the rules for this scenario don't fit modern F1, partly because they haven't needed to be used for quite some time, and committed to review and update in consultation with teams and stakeholders.
Honorable mention to Bernd Maylander going out there in a road car, albeit a high performance road car, and pushing it to the limit in squeaky bum conditions to lead maybe $100 million worth of cars around a couple of laps.
If it hadn't been a back to back with Zandvoort running the race on Monday might have been more of an option. Even then, marshalls would have been a problem. They are volunteers, it may not have gone down well at work 'Boss, I can't come in on Monday. I have to go to Spa to wave flags for Max Verstappen".
