Here are a couple of recent articles relating to autonomous vehicles, simply underlining the inexorable path we’re on to deploy this technology at scale, and its clear ability to overcome any obstacles in its path.
Firstly, California is going to allow autonomous vehicles to operate WITHOUT human drivers. There are many terms & conditions here, but this is still a huge step forward in overcoming regulatory hurdles. Regulatory hurdles are one factor that has the potential to slow adoption.
Secondly, battery technology continues its rapid evolution. Toshiba has announced updated battery technology that offers extreme reliability & safety AND 320 km (186 mi) range from just 6 minutes charging. Amazing!
