Whoopsy:

They were never serious about it to start off with, they only went in to 'look green'. 

Recently attended Formula E Seoul invited by local Porsche dealer and walked out half way into the main race.  Just no drama other than 8 car crash pile ups.

On the way out, I saw multiple diesel generators used to charge these Formula E cars.  What a pity!  

It's just all for a show and not even a good one.
