Not sure of why there'd be so much opposition, but I'd want to see F1 to remain as the pinnacle of autosport, technology and racing.
All Electric Drive-train, with Batteries have better potential for performance than normal IC engine systems. Better Torque curve (Straight line in fact), Battery technology improving rapidly, Sounds great (Star trek sounding), Better Reliability (fewer moving parts). Better Braking (Reverse polarity of AC motor), In-wheel motors mean better balance.
Potential to rotate each in-wheel motor at different speed at maximum torque. Data Acquisition would be very simple too.
And all the Aero development work can be kept with a few mods.
Actually, If I had a few hundreds of millions lying about I'd be considering building my own series! Futuristic and Clean.
Tho in the new series I would limit the size of the car so that overtaking would be easier.
I'm no Hippie, Coz I know even if this stuff happened, it wouldn't save the world, simply because there are not enough power plants to take on the power to run Electric cars.
