Auto giant Ford said on Tuesday that it will conduct blockchain monitoring and implement a fuel-efficient driving mode for the German team in Cologne. The program will be synchronized in London and Valencia, Spain. According to reports, Ford cooperated with the city of Cologne to equip 10 plug-in hybrid vehicles with cellular modems that support geofencing. When the vehicle enters the low emission zone, they will automatically switch to electric. Metadata such as when the vehicle enters or leaves the area and the miles traveled will be recorded in the blockchain.
