I'd argue gear changing is not about driver skill. It's due to shortcomings of the RPM-range of the engine. One pedal for accelleration +/- and a steering wheel is all you need. Or maybe a separate pedal for braking. Everything else is "Nintendo".

Nissan Juke AWD rear diff does it... Its not beyond the F1 teams ability. I think it would even be legal under current rules as the driver already has the ability to change the diff settings. it would just be moving them to a digital-proportional trigger instead of a turn-knob.Tommy Cookers wrote: ↑24 May 2026, 19:43aeroplane drivers have been doing this for 100 years ie differential braking (also differential throttling)
it seems implausible to use one MG via some weird, complicated and wasteful mechanical variable differential .....
when two (smaller) independent MGs could be used without any mechanical differential
signal arithmetic ie summing & differencing small voltages is far better than summing and differencing actual forces

That's the argument Lucid make for their double rear MG as well.Tommy Cookers wrote: ↑24 May 2026, 19:43it seems implausible to use one MG via some weird, complicated and wasteful mechanical variable differential .....

(manual fiddle brakes were/are eg a key part of trials driving UK-style)
it works by wasting energy

And splitting between 50/50 and 0/100 doesn't seem to be much of an energy waste. (some I'm sure, but minimal if you compare the AWD vs FWD mpg statistics)

so I looked at Nissan Juke AWD
did you mean Nissan Juke AWD-V ?
(yes there is such a thing)
