Not the only company this can be said about, but Apple has lost its focus. This self-driving car baloney is evidence of that. Let the automobile manufacturers worry about vehicles, and let the computer companies focus on computers. Apple is stretching itself way too thin, with hands in multiple cookie jars: automobiles, media production, smart devices... oh, and maybe a couple of computers, if they have the time. It's greed and hubris, plain and simple; Apple's eyes are too big for its stomach.
Not to mention, no one has made a valid argument for what's so great about self-driving cars anyhow. For all the complaining people do about the dangers of humans behind the wheel, I don't see how computers are an improvement. The human brain is still light-years ahead of the most advanced electronic circuits in its ability to comprehend, adjust and integrate the multitude of information received when driving a vehicle (or performing any other complex task). For all its potential shortcomings, I'd trust my life to human judgement than a machine algorithm any day.
