Racing EVs can be fun to spectate, even more so than petrol cars in slow corners. It's all down to design choices, the only real issue is sound as mentioned many times. Not like we haven't seen that before with "silent" N4 evos.

If by "current motorsport audience" you mean european men of 50+ age then that is true to some degree. But only some, as mentioned quite a large part of people buying Tesla 3 are previous BMW 3-series owners. Which is a typical "cheap" motorhead car. Even in CZ with almost no electric cars you got people actually attending the EV "rally" (with normal EV cars) for "motorsport" competition. That doesn't fit your narrative of people that buy electric not being interested in automotive competition.

But it's the boys of 10-15 or even less you should look for real future. And those often already look at petrol car as something that is too slow and unnecessary complicated. "Why drive this petrol car when that Tesla/Porsche Taycan/Rimac etc. is faster?" That's like using dial-up internet instead of fiber broadband because you like the modem-connecting sound. The same kind of boys that buy an electric drone and go racing with it, rather than making rc plane with petrol engine from scratch.

This is the kind of trends you start seeing when there actually are many electric cars around. (here for last 3 months over 50% of new car sales are electric).
