I don't know much about the space so let me know if I'm wrong, but from my point of view there's still a world of difference between all devices working on a packet network (that's simply efficient) and having ten cameras filming surveilling everyone around me continuously and executable code being pushed to my vehicle over an always-on connection that I have no control over. And then on top of all that is tactile controls so you don't need to avert your eyes or pause podcasts to adjust the windscreen wipers.
