I suppose as it's going in a real vehicle they wanted something reliable hence avoiding the Thrustmaster options?
I can't help but assume that Apple autonomous vehicles will only work on Apple sponsored roads and will only recognise other Apple autonomous cars, leading to a lot of collisions that would be blamed on the Google cars for being incompatible with Apple iDrive?
iDrive would also be quite an ironic name for a car you don't actually drive. Although I suppose BMW has taken the iDrive name already...
A Fanatec CSW was installed in passenger side of a Pikes Peak Hill Climb race entry, with a similar function.
Car was piloted by a paraplegic man, with electronic interfaces for steering, throttle & brake,
and the back-up driver sat beside him with the Fanatec, just in case of a problem.
