Always makes me laugh when you get some dimwit that claims the Earth is flat, but then uses Google maps in his car. Magic!

GPS are amazing. If you understand how they work, and how they reliably know the time etc. you'd think you live in the future; and yet it's everywhere, in our pockets.

Don't you know, the Google maps team is part of the conspiracy. They calculate everything assuming a flat earth, they just don't tell you that.
