What have been the most dramatic changes in passenger transportation over the centuries?

Explanation:

The invention of the steam ship and especially the railroad. It increased both the speed and amount of goods.

Iron hull steam ships could be made far bigger than any sailing ship, and faster. Even the fastest windjammers would only average 8 knots or so overall, even if they could do burst of speed for 16 to 18 knots, and sailing ship.were always at the mercy of the wind. Steam ships could travel at a steady 6, 8, or even 10 knots or higher and were not at the mercy of the winds. Trains could travel in a day what a horse drawn wagon might take week, and loads of far greater size. For the first time in history, transporting by land became as cheap as by sea.

The airplane, of course, allowing you to reach places in a day what could have taken a week or more.

And the automobile. It changed the structure of cities, allowing one to travel easily 25, 50 miles, even 300 point to point wherever and whenever the driver wanted, not to someone’ else's schedule (train, plane, ship) and destination.
