Do you realise airplane controls are fly by wire? And they are much more succeptible to particle bombardment related errors due to their height? This is not a valid argument.
Drivers of our generation arent ready for joysticks. Thats about it.
For the amount and cost of oil we'll have in 20 years I'm betting most of it will be saved for flights and trucks and such and most of us will be walking, biking or taking trains...that's my guess anyway.
I agree that a mechanical linkage between the driver and the steering wheel is an essential safety feature.
Only if a fully redundant backup system is available would I consider switching to a fly-by-wire clone in my car.
The day we use something like Microsoft Windows to control our new cars is the day I go out to the junkyard to buy and retrofit an old car.
Even in more "robust" RTOS operating systems I find glitches and problems that require reboots to clear problems.
This is exactly the point, planes are flown with a 1000m safety distance in X & Y, and something like 300m in Z. Our roads have as little as 50cm between vehicles. The additional risks associated with joysticks in planes are mitigated because of the 3D nature of flying. I have read news reports of drive by wire throttle control preventing a driver from stopping his vehicle for about 40km until he crashed it to end the nightmare.
In airplanes, if you drift a few degrees left, you likely aren't going to smash into anything or fall into a ditch. Much different in a car.
That said, I could imagine an electronic "steering trim" control for long highway stretches, maybe tied to a vision system to follow lane markings...
And how about this? Hacking a car through bluetooth... not easy apparently, but possible.... scary....
