Leather flying helmet obligatory for mid winter top down driving for (follicly challenged) me irrespective of number of wheels.
We were on our way back from the Portsmouth ferry in 2019, when we saw a man driving a modern Bentley Continental convertible, hood down.
He was wearing a leather flying helmet and goggles!

Each to his own.
