As Core77 points out, the way this concept dashboard from Johnson Controls presents the speedometer is sort of hurdurrringly obvious:
While the bulk of the dashboard is ho-hum, at least one new detail is worth looking at, the speedometer gauge. While the gauge to the left of it has the conventional center-mounted needle, the large gauge has a "ring pointer," where the pointer is a graphic on a clear, rotating ring. This simple design innovation frees up the center of the dial so you can display more information.
They could also have the indicator locked to the twelve-o'clock position with the numbers themselves rotating, although it would probably be a little more difficult to visually parse the spaces between the hash marks.
