A meeting point is only fair if both drivers know what they are signing up for. Here is the context at each end of the 1411.2 mi drive.

Modesto keeps Pacific time and Sioux Falls keeps Central — a 2-hour difference. Drive times are clock-agnostic, but wall clocks are not: leave Modesto at 9:00 am and, after the 22 h 03 estimated drive, it is about 9:03 am the following day in Sioux Falls. Clock-change weeks can shift this by an hour.

Driving between Modesto and Sioux Falls costs an estimated 22 h 03 behind the wheel. The great-circle distance is only 1331.3 mi; at a 460 mph cruise with 90 minutes of airport overhead folded in, flying works out to roughly 4 h 24 gate-to-gate — an estimate, not a schedule. Airport transfers, security, and boarding eat some of that edge, so the honest comparison is 22 h 03 of driving versus about 4 h 24 from curb to curb when the connections behave.
