BMW is in the midst of celebrating its 100th anniversary, and to mark the occasion, it just rolled out the Vision Next 100 concept at its Munich headquarters.<br />If you squint your eyes, you can still see a car that's clearly a BMW here - it has the iconic "kidney" grille, for instance - but beyond that, the details are all visions of a distant future.<br />As with other recent concept cars , the Vision Next 100 refuses to take sides in the self-driving debate - when you want to drive, you can, and the car helps you by drawing the optimal driving line on the windshield.<br />Very, very little in this car is anywhere close to production-ready, but put together, it's an interesting mix of tech that BMW thinks will define the next few decades of its existence.
