It will have simulated gear changes if that helps at all...
That was potentially 36 years ago. 36 years from 1990 would have been 1954.
What changed in technology from 1954->1990, vs change in technology from 1990-2026? Quite a lot.
Because of the electronics. They're vastly different, there's tons more, and they're proprietary.
The only successful vehicle which has that is a driver-training car built in China. It's electric, but has a clutch pedal and shifter which are inputs to the software. You can even "stall the engine".[1]

I think by simulating a transmission you mean those internal combustion engined cars with CVT transmissions. Those are terrible yes.
