Oh, I don't dispute that maybe very modern cars have addressed this. I don't swap cars too often and have been pretty happy with my "one transmission, a planetary reduction gearbox" car (maybe there are 2 transmissions, one on the front motor and another on the rear motor? Regardless, there's a static gear ratio that's always engaged).

The lag is only part of the issue -- it's the determinism of the lag -- the 125ms lag between "more power please" and getting more power is actually more lag than the instant ka-chugachug of asking for more power and getting feedback of "you're in the wrong gear, bubba" if you're in a manual transmission car.

As far as "I won't change gears for you unless you ask" transmissions -- I've never driven such a car, I'm sure they're quite nice. I somewhat dislike the gear changers with no affordance to indicate what gear you're in (this applies to wingding manumatic cars, motorcycles, and modern bicycles with thumb / finger triggers) -- I don't use them often enough to have the muscle memory of "up for lower gear ratio" or whatever, I have to think about it and look at an indicator and fiddle with it to get the right ratio for what I want.

I'm sure with practice it would eventually be fine; but in actuality I've found that the electric car is actually exactly what I want.
