That race in France in 1894 is one of the earliest known instances of a wheel-shaped device being used to steer a car. In 1898 the French manufacturer introduced a steering wheel in all its models. Other manufacturers followed suit – and the steering wheel became a set part of automotive design. Early on, carmakers also began installing bulb horns on steering wheels, for as traffic increased, it became necessary to warn other drivers as well as pedestrians and cyclists.<ref>{{Cite web|last=Patrascu|first=Daniel|date=2010-05-05|title=History of the Steering Wheel|url=https://www.autoevolution.com/news/history-of-the-steering-wheel-20109.html|access-date=2021-11-14|website=autoevolution|language=en}}</ref> For about two decades thereafter, steering wheels were incredibly simple: wooden circles directly connected to the wheel axis. They served no other task and could be extremely hard to turn, especially at low speeds or when stationary. Though power steering patents were circulating as early as the steering wheel itself, it was quite a long time before these systems were used. In the 1920s, an engineer named Francis W. Davis wanted to make truck driving a little easier and invented the first power steering system to be fi
