The user interaction analysis on the page points out that people in transit stations don't have the same preconception about interface. In a noisy, dirty, worn out environment, people presented with a durable looking machine with shiny labeled buttons tend to use the buttons and not the screen.

I agree, using it on the internet I kept clicking on the "screen" instead of using the buttons.

Though, I do find myself occasionally futilely poking at ATM and gas-station screens that were made years before touch-screens became common.

But why break the already-established custom of big black arrows that point at the buttons every time you need to use one? I barely even saw the letters on the map.
