I've done this. I've flown across the Atlantic and have driven cross-country, both with paths that make sense only in the globe model. The southern hemisphere simply doesn't make sense with the FE map. I know if I give an example that goes over an ocean you'll just say it's part of some gigantic conspiracy, so how about something people simply drive across? Look at Australia here and tell me which path you think will be shorter, red or green. (No cheating and looking at a globe.) By the FE model, this should be really obvious, and anyone taking the green route should be at least a hundred miles out of the way, right?
