A lot of people would tell you it's about the mid-term application of Artificial Intelligence for 1) connected and autonomous electric vehicles and for 2) the wider scope of smart mobility and traffic flow management.
But I would recommend to not get carried away by any "hype topic". Technology progress is a matter of extremely hard work and incremental improvements. And it's way harder to achieve than the impression raised by even highly renowned scientific publications, not to mention mainstream media.
