In one word - Ferrari
When we think of Italians in America, New York City’s failed Mayor Blassio pops up, or the present Speaker of the House but not of men in the shadows like Filippo Mazzei who shared his ideas with his closes friend Thomas Jefferson and is credited for the line, ‘all men or created equal’. Or we may think of famed Hollywood directors, or of the black market controlled by the Mafioso but it is when we think automobiles, the Grand Prix, the Formula 1 cars; then a different picture comes through.
You see the Italians have a history not only in politics and arts but on science and invention from the days of Galileo and Leonardo da Vinci. LV sketched among many things a flying machine with retractable landing gear so it should be of no surprise that some of the subtler engineering talents are in Italy and therefore in the automobile industry, the Italian Ferrari followed by the Lamborghini. These companies with their racing cars not only contributed to innovations in the automotive industry but also to the American psyche and a love for fast cars. Suddenly, the automobile turned from a transportation cart to an experience of ‘near flight’ for the common man. In US, if you want to date, you need a car. (Archie’s comics became famous for teens because it carried subtle messages on dating – like avoiding a jalopy).
Now guys may say, ‘okay’ but remained unconvinced since ESPN covers NASCAR and not Formula 1. It's also true that NASCAR drivers use 'cars of tomorrow' and therefore are proofs of technology that contributes in any big way to one of the largest manufacturing sector in US (and in the world GDP).
In my opinion, it's the F1 cars, lighter vehicles that contribute to 'concept cars' and direction technology may take.

The defining criterion, from above article, in my not-so-humble opinion is that participating racing teams have to build or construct (assemble) their own cars - for speed / safety. NASCAR teams drive from stock models.
Renault F1 team is credited with introducing several new design models for both the racing industry and transportation industry as a whole. Their concept cars, which range from electronic cars to ones with zero emissions, and even one accompanied by a helicopter drone.

Here’s another article to muse over.
Mercedes surprises with innovative Dual Axis Steering system
https://www.f1technical.net/development/22329/mercedes-surprises-with-innovative-dual-axis-steering-system
It talks about the steering wheel which slightly retracts forward and backward while approaching a curve or coming out of one – an example of tech thriving where competition is – in the racing world.
The competition for US market share has always been between GM and Ford (Chevrolet, Chrysler, Cadillac are divisions in GM) - till Honda entered strongly in the 90s.
The competition in F1 racing has been between Mercedes-Benz (Germany), Ferrari, Jaguar (UK), Lamborghini (Italy), till Honda entered in 60s, abandoned and re-entered as Red Bull in 90s(?).
Formula 1 racing cars are expensive and their financing is by consortiums that include American car manufacturers - so in this sense, new technology is shared
Ferrari: About 25% of Ferrari shares were held by Chrysler Automobiles and FIAT till recently when they sold these shares to individual shareholders
Red Bull: has a deal with Ford, is owned by Honda and manufactured by Jaguar (UK)
Special note for Tom - 'what do you think?'
