All I can say is that the other week, I caught what looked like F1 racing on TV a couple Saturdays ago in Brazil---- but as I watched the cars, all you heard was a:
zzzzzzzzzzzzZZZZZZZZZZWWWEEEEEEEEEEEEEEeeeeeeeeeeeeeee as each car passed. That was when I realized that they had eliminated 90% of what makes car racing exciting--- the hundreds of subtle micro-tuning adjustments to engine, etc., to gain optimum performance. It was a joke.
All that was left I suppose was to try to optimize the wheel motors and maybe the battery. It was literally boring. There was movement, but nothing going on.
If/when NASCAR goes all electric, it will be the death of the sport in large part losing a great deal of its audience to dullness.
