What about what is on those billboards is false? It is a circle, but you can only drive one way. Would you find it a more accurate representation if the street you drive in on was a straight line?

Personally, having sat in the traffic that is LAX, I'd much rather the DL terminal be one of the first hotel/parking shuttle stops than one of the last. Being able to get into the airport quickly is usually more important because that's where people tend to face the biggest time crunch rather than when they are leaving the airport.

You're really reaching with this complaint. But, hey, have fun riding to United's terminal.
