*"just for kicks I held my hand out the car window while driving at about 80kph / 50mph"

Do that on the M25 and you won't have to worry about gloves ever again !

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
