Which Came First, Traffic Lights or Cars?

[FrankRose]

Traffic lights came first. Here is the relevant introduction about which came first, traffic lights or cars: 1. The invention of traffic lights: Traffic lights were invented in 1868. The invention of traffic lights predates cars by 17 years. However, traffic lights were initially invented for the passage of horse-drawn carriages and had nothing to do with cars. 2. The invention of cars: The earliest cars appeared no later than 1885. In 1885, German engineer Karl Benz built a three-wheeled car in Mannheim. This car was equipped with a two-stroke, single-cylinder 0.9-horsepower gasoline engine. Because it featured some basic characteristics of modern cars, such as spark ignition, water cooling, a steel tube frame, leaf spring suspension, rear-wheel drive with front-wheel steering, and a hand brake, it is considered the world's first modern car.
