automated cars would obviously eventually become faster than F1 drivers, it's just there's no interest in it (unfortunately).
The biggest interest to most people are the drivers and they strongly dislike driver aids. I'd prefer every driver aid under the sun and have a real engineering battle. I'm obviously in the minority here.
Formula E is under very tight budget constraints in order to lower the barrier to entry. I look forward to the day when the series is established and they can start to compete on things like motor construction and battery tech to drive the field forwards.
The racers like whatever makes them go faster. When ABS and traction control was allowed everyone was using it. It just made you faster. But the current rules ban them with the goal of trying to make the driver matter more.
One of the sports all time great (Micheal Schumacher) won all of his championships with traction control most likely. The teams used their own computers in the cars then so it was basically impossible to police and thus the ban was lifted in 2002. The ban was put back in place when the onboard computer in the cars was homologated (everyone uses the same computer by McLaren)
