Why BigTech (Apple, Google) Is Scaling Back on Self-Driving Cars.

I originally published a version of this post in June 2016. This update, with the recent news, further confirms some of the assumptions I made back then. The tweet above confirms something we're all quite aware of, which is that there is still a lot to do before we get self driving cars onto our roads. But why is this the case? Aren't these companies the ones with the technical know how and unlimited resources required to make our self-driving car fantasies reality?
