Moreover, Technique X does not actually provide any significant value.
The whole steer-by-wire in CT happened because Musk wanted a yoke as the control system. And a yoke requires progressive steering which is impractical without steer-by-wire.
steer-by-wire makes safety nannies way easier, eg, the ones that jerk the wheel out of your hands when they decide you're too close to a line on the road.
Other models got the yoke but not the steer by wire.

If that were true, it would not explain why other manufacturers are headed the same direction. The CT is not the only steer-by-wire vehicle.
