I'm not really sure Formula E is big enough yet to put a lot of resources into battery tech like Formula 1 can engine tech.

I believe the biggest reason they are in cities now is that the battery capacity/tech just isn't there yet for something like Spa or COTA for the distance and speeds required for an interesting race. City courses allow for a design that offers a lot of regenerative braking.

Another reason to host them in cities is that cities are great for fans. Lots of hotels, restaurants, people buy tickets, etc. Cities are likely more open to Formula E due to the quieter cars and lower pollution too.

So, not useless, just maybe not interesting to you.
