Cars- It's true that a Frenchman made the first gas engine car, and that some of the very, very early cars (which were unaffordable and unusable by the masses) came out of central Europe. Nonetheless, it was US innovations that led to cars that were actually adopted by significant numbers.
Airplane- I really don't know what you're getting at here. From the Wright brothers' first flight to the mass adoption decades later, the US lead the way.
Web- The web as we know it started with Mosaic, which came out of Illinois. Even by 1995, the vast majority of internet users and sites were in the US. If one were to be pedantic, Lynx which came out of Kansas could be considered to be the start. I can only assume you're pointing at Tim Berners-Lee, who made the initial proposal for the protocol and a few proof of concept tools. He's an Englishman, but has chosen to do his work in the US out of MIT, which only goes to show the strength of the OP's argument.
I still stand by my remark that being seriously upset by that line in the article is an indicator of being out of touch with reality.
Yes, Ford invented the production line, he did not invent cars.
> From the Wright brothers' first flight
Flight had been going on for decades. There is some evidence that a New Zealander did controlled flight under power first (which is what the Wright brothers are generally credited with), but did not publicise it. Wing-warping was already under trial in Europe at the same time as the Wright brothers; the Wright brothers' innovation was to get to the patent office first. (I don't share people's kudos of the Wright brothers. They got too much credit for what was going to happen anyway within weeks in Europe. They were extremely aggressive patentors and did much to suppress innovation by competitors.)
> Web
Berners-Lee invented the Web. Pure and simple. Other people made tools that used it, but that was not the claim.
