Why not? Why can't there be a solution where you own and control your data to the full extend? Load an offline map, drive to your location, park done. Car GPS have done this for ages. I can't see why your future self driving car shouldn't be able to do the same. Heck, even if you download a current update of the trafic around you over the air, privacy _could_ be baked right into the product. It's not that we couldn't. It's waaaay more easy just to integrate your favorite cloud based engine, I see the pluses of that, but I also see the big big minuses attached to that.
