In my EV it literally is a potentiometer. I really miss the feel of a physical throttle linkage on the snow and ice, I feel it's much more difficult to judge grip.
Also, since it's just a pot, I don't know why there's not a speed mode for it, it to make it operate the cruise control speed set-point rather than torque.
The throttle is separated from the wheels/ground by the transmission and the whole engine, which makes me wonder if the response you felt probably was a combination of eg rpm/physical vibration and a few other factors. It should be possible to recreate these even in an EV, then.
I did learn to drive manual, but I'd never buy another car like that. Maybe it's fun for racing, but for every day driving, automatic requires less effort and longevity isn't a concern today.
Manuals proliferate in EU, but we have also always had automatics on the road - and a significant increase since DSGs hit the market - so no one who has driven a few normal cars would be surprised by two pedals in an electric.
