Car: Four years later in 1885, Karl Benz designed and built a car powered by gasoline. This car was made in Germany. This was the first ever car to be granted a patent in 1886. The rest is history and the world acknowledged Karl Benz as the "Inventor of the modern automobile". He also invented the first ever car with an internal combustion flat engine in 1896.
Airplane: Many people worked on various kinds of planes over the years, so no one person invented the airplane.
Gun: The Chinese had the first handguns, "fire-spears" and handcannons, technically known as guns with a "canon lock". Da Vinci just designed a "Automatic Igniting Device for Firearms", a more sophisticated kind of matchlock.

4.5/12 isn't so bad, isn't it? Especially coming from a self-entitled American such as yourself, who just automatically assumes everything he uses is invented by his countrymen. How about actually doing some research beforehand, eh?
