And Formula E comes with its 4the generation, becoming closer to actual F1, but with more acceleration

I think the big failure of formula e was the way they failed to promote pit replaceable battery packs.

It is debatable how much motorsport tech trickles down to improve our daily motor tech, I think this was much more the case early on and now days the sport tech is so rarefied it does not help us much. But mass market electric cars are still fairly new and I think that sporting competitiveness can do a lot of good here. The big one that was missed were easy to replace generic battery packs.

But I also think the biggest failure in f1 was the removal of refueling, so what do I know?

footnote: in nascar it was the five bold lugnuts, the pit stops with five bolt lugnuts were absolutely gorgeous compared to the single bolt they use now... and we wept.
