Trivia: Which vehicle measurement tool was originally purchased separately?
Correct Answer: Speedometer
So why is this answer correct? : The speedometer, or the gauge that measures how fast your vehicle is going, now comes built into your purchase — but it wasn’t always that way. Without strict, modern road rules, vehicle owners traveled at their own pace, and the first speedometers were optional purchases. The speedometer was invented as early as 1888, but wasn’t officially patented until 1902. Beginning in 1901, speedometers were built into cars.
