Like pretty well everyone here my wife likes them on.
But I really like driving with the side screens off, and my flying jacket helmet, gloves and goggles on - full prewar Biggles mode.
Got myself a stick on Walrus Mo and and a pipe too but am yet to use those, I think a pipe gripped with the teeth out the side of the mouth really adds a certain whatnot. And in practicing with it I believe pointing the mouthpiece at things or tapping it on the table for emphasis seems to add a sense of authority too. Saving those two items for when Tasm3W gets his three wheeler in a couple of weeks and he takes me for a blast.
I do love the look of the car with the roof up as well as screens on though, very 30's B&W movie look.
