I'd say windshield wipers were more roll. Unless your windshield is lying flat.

Simply put, when you turn the steering wheel on your car, it results in a right or left yaw.
Which reminds me: some guy named Hatfield rode his explosives-loaded mule into a residence housing a bunch of McCoys and blew the place up. Were any of you aware that the Hatfields had declared another gee-hawed against the McCoys.

Dang it, when will you people learn to read my mind?! When I said windshield wipers, I was imagining two centerpoints in the windshield (one for each wiper), and the wipers moving to the right and to the left of these. Or, let's just say one centerpoint and one wiper. No downward or upward motion at all, strictly right and left? Like Ted said--I hope?

On my car there is upward and downward motion on the widnshield wipers. That's because my windshield has up and down to it. Now maybe if you had wipers on your sun-roof…
Attually® on most windshields these days there is roll and yaw going on, cause the windshield isn't straight up and down.
Your turntable is all yaw. (you remember turntable?)

The movement of windshield wipers is definitely roll. Yaw would be if someone hit your car and it spun around in a 360. Pitch would be if it went end over end over the guardrail. Double roll would be the windshield wipers plus the car rolling over on its sides.
Probably not related is thinking about musical pitch going up and down. I think of pitching a roof--taking it up high--and musical pitches. And that ship pitching over the waves--its bow rising and falling over the waves. Would the pitch of a ship--the origin of the word--have anything in common with musical pitch?

Or the ship or the egg? Shakespeare wrote about "enterprises of great pitch and moment" so our search for "pitch" would have to start long before that. The longer the pitch, the deeper the mystery.  BTW "perfect pitch" is a very rare thing. The last perfect pitcher I remember is David Wells against the Twins almost 6 years ago (May 17, 1998). Going back to the origins of "pitch", my guess is they were pitching woo long before sailors were pitching and tossing at sea.
