Wow, that would be a departure. I thought the US required direct mechanical steering and brakes on all cars. If this is the world's first steer-by-wire, well, I have think hard about whether I'm ready for that.
There's probably an electric brake pump that provides boost pressure, like a Prius.
Likewise, an electric steering pump for that overboosted steering feel.
Next time someone does a drive, try cranking the wheel over while the Leaf is off. I'd bet it feels pretty normal -- heavy, but mechanically connected.
