You are right. I guess I will never fly commercial again. If their computer goes down, the steering will not work.
They’re defeating the whole purpose.
There is no ‘the computer’. Planes, and probably the car, have a LOT of computers. One can fail, several can fail, and the plane is still controllable. The probability for more than one failure to take out a plane is astronomically high. I am not just saying that. In the avionics industry we have to do the math and KNOW how likely is for something to completely take out a flight critical system. Is the Google car developed to those standards? Can they prove it? I highly doubt it.
