Formula-E is also known as "Formule No-Engines therefore nobody watches it". Sad but true.
One of the big reason people pay to watch motorsports is for the noise and rumble of ICEs. It's no coincidente that Formula 1 kept loosing viewers and money the more cylinders they were reducing for the sake of "environmentally friendliness", even though the carbon emitted by their V12-V10 ICEs was dwarfed by the gargantuan amount of carbon released to move that circus across the continents all year.
So unless you ban ICEs in motorsports as well, I don't see how you can convince investors to spend big money in Formula-E development, considering how little viewership it generates, in oder for it to spawn cutting edge tech that can later trickle down to road cars like it was with F1 decades ago.
