One of the more inspired design choices of the parking ticket devices in my area is the inclusion of a key repeat feature. If you keep your finger on the touchscreen for just long enough, it helpfully repeats the keystroke while you're entering a license plate. Given the inevitable hardware issues, this means that what should be a single tap frequently becomes a burst of identical characters. The programmers who worked on this probably would've liked to be game developers instead.
