Technologies pioneered in F1 have made their way into our lives over the decades, not just in the cars we drive, but in fields as varied as pediatric surgery and air traffic control. Every car you've ever driven was more efficient due to something that was bleeding edge in F1 years earlier.
I'm not an expert so I couldn't say how but I would be amazed if their current work with hybrid drivetrains don't improve EVs.
Yeah, F1 burns a lot of gas, but calling it "just funsies" is short sighted. If you add up it's effects over the years it's a net positive and it's not even close.
