Just a small correction-- Formula E doesn't swap cars anymore, they go the full race distance now, although the distance is much shorter than Formula 1, for example.
I wonder if any electric cars are going to get swappable battery packs? That way you could get an instant recharge, and for racing, it would make battery pack heat manageable by just swapping out the hot pack. It might even provide an advantage over ICE race cars, as fueling is often the lengthiest operation in pit stops.
They have given up on that, and there are certainly some problems with the model (for example, what if you own the battery, and they replace it with one in poorer condition?), but other companies are still pursuing it: https://electrek.co/2018/11/01/nio-battery-swap-station-next...
