In your mind, how many years is a few years? I watch Formula E, but it's hard to imagine it becoming the pinnacle of motorsport anytime soon.
Formula E's definitely made progress: e.g. they no longer have to run two separate cars just to finish the race, and they are decently quick. But they're still pretty far away in other aspects: 45 minute race, on temporary circuits purposefully designed with many tight turns to allow for braking regen. Battery technology has to improve quite a bit if you want to see electric cars turning laps at Spa at standard race distances.
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).
