Formula E has also made the conscious decision not to pursue open chassis and aero regulations - good for keeping the costs down, but it makes it harder to take it seriously as a potential future 'pinnacle' series.
That being said, the attraction to manufacturers coming into FE is large and it'll only take a few more generations before I'm sure there'll be differentiation in some parts.
I'm bullish on FE, especially when they can run on "proper" circuits at a consistently decent pace (that being said, smaller city-centre tracks might very well be the future of the sport in any case).
