The Bugatti Mistral is a Chiron-based roadster. So what happens if the driver encounters a rainstorm? This person creates a makeshift roof out of a Bugatti-branded umbrella.
Of the possible solutions, this seems like the best choice. The umbrella balances between the windshield and the rear nacelles. The driver is going slow, so there's no concern about the wind blowing away the umbrella. Also, it appears to be just sprinkling rather than a downpour.
