Would it make 4WS an easier thing to engineer?

Of course, Honda already had the 4WS steer with the Prelude and it was very good indeed.

Electric motors in the hub, every wheel is independent and combined with 4ws you could turn the car in its own axis. Cool...
Nissan said that users would benefit from an improved driving experience since their intentions would be transmitted to the wheels faster than by using a hydraulic and mechanical system.
Mechanical systems that directly connect the steering to the wheels? In real time?
Electric is faster than real time?
That's impressive.
Although given they use the word "intentions", do they assume that the steering could turn based on what we plan to do rather than before we move our hands?

It's faaaaar easier to kerb the rears with 4WS, if you think about it. I think the Nissan 4AWS & Honda PAWS systems dispense with the easy-park facility, because most fine it harder to park with it! You can tie yourself in knots round the back bumper of the car in front, until you get the hang of it.
But yes, the principle of 4WS is essentially DBW; front and rear angle sensors, a speed sensor, a rate of steering wheel movement sensor and an algorithm to sort out the required input for the rear rack. A far cry from the clever mechanical 4WS of the 3G 'Lude! It wouldn't have been a massive leap to lob out the hydraulics in favour of an electric front rack, too.
Did SAAB not have system that was controlled by a Joy stick for steering, obviously a DBW system.
Now there are not an awful lot of aeroplanes flying around with FBW but we keep hearing of software problems etc with those, so what will happen when millions of Nissan's ( Incorporating Renault Electronic's ) hit the road, It just might like an evening on the dodgems at the local fair !!

Yes there have been one or 2 high profile cases like the A320 chainsaw incident, but there are also plenty of incidents of 737s going down.
I have handled literally thousands of these aircraft and have never once encountered a FBW related incident.
