The European Commission has been urged to come down on the side of C-V2X in the standards war embroiling V2V (vehicle-to-vehicle) and V2X (vehicle-to-anything) communications by a sizeable group of major auto OEMs, telcos and infrastructure providers. This urgency to make a choice highlights the emergence of platooning as the likely first commercial realization of autonomous driving with potentially significant fuel savings for fleet operators – combined with reductions in congestion. Platooning saves fuel costs by exploiting the same aerodynamic factors that make longer trains more efficient than shorter ones, the same one that racing cyclists exploit by shielding their best rider behind others to reduce air resistance. According to the European Union (EU) SARTRE project, running between 2009 and…
