When I was young one of my uncles had some foreign job of a car
The speedometer was a very strange design...the needle was stationary, and behind it was a wheel which turned to display the proper speed
Only issue was, when you drove it in reverse that wheel would turn backwards, showing you were doing 120 while backing up
(Couldn't find a video of one backing up, but this is what the speedometer looks like...the tach worked the same way)
