FACINATING, Thanks Jonco!
I love it when I learn something that I’ve always wondered about. Thanks for finding and posting this!
Great explanation!
Very interesting. Now can you explain how the gears work that force my car to turn towards work even if I am off that day and going to the Post Office?
