I just don't really see the advantage in it, personally. The car has a mechanical linkage anyhow as a backup, so it's not like they're eliminating complication, weight, or parts. Just the opposite, in actuality. Then you have the issue of trying to make the driver actually be able to feel the steering, which required additional devices to simulate feedback since there is no actual connection between the wheels and the steering wheel.
Think of it as a test platform. In 10 years when they have enough data/testing/etc. they will try and eliminate the actual steering column citing the reliability of this system and the the increased safety from removing the column.
Do airplanes have mechanical linkages to the flapper thingys?

I know that was rhetorical, but for the record yes/no.
civil aviation still has a lot of cable use. big commercial planes with surfaces so large that a person can't generate the force to move? no
Jeez, I'm still annoyed with throttle by wire and this is a thing now?

No they have a properly redundant system, which is the only way to safely do something like this(or steer a car) with a computer involved. Basically, there's three or more of everything, all independent to varying degrees, so even if one circuit goes completely AWOL, the others will be strong enough to overcome it.
You can read abut how Boeing did the 777 here http://www.davi.ws/avionics/TheAvionicsHandbook_Cap_11.pdf Sec 11.6 "Fault Tolerance" is particularly pertinent.
