   • 1962 December, “Talking of Trains: Derailment at Lincoln”, in Modern Railways, page 375:

     Although it might be thought that drivers would naturally refer constantly to the speedometer, older drivers who come to diesel driving after years of steam experience without the help of speedometers, as well as those on steam engines which have been equipped with speedometers in recent years, have not accustomed themselves to the constant use of this instrument.

   • 2022 September 10, Matt McFarland, “Why your car’s speedometer goes up to 160 mph (even when your car can’t)”, in CNN Business‎:

     But even Apple, the company that cast aside tradition when it reinvented phones, music players and headphones, bows to convention when it comes to speedometers. It displayed a classically-styled speedometer that reached 160 mph, an auto industry norm.
     That’s nearly twice the highest posted speed limit in the United States, 85 mph, on a stretch of highway in Texas. Why do our speedometers stretch to a speed that’s illegal, and only race-car drivers will ever reach?

2. Such a device incorporating an odometer.
