Volkswagen chief executive Herbert Diess said Monday it was "impossible" for the German car giant's electric transformation to happen any faster, but he accused Angela Merkel's government of holding back change with generous diesel subsidies. I would question that," the 62-year-old Austrian said, adding that even electric car pioneer Tesla took over a decade to get going. The "dieselgate" scandal saw the popularity of such cars plummet and hastened the electric revolution, but diesel prices have remained relatively low. But Merkel could have been "a bit more decisive" in some areas, the CEO said, such as incentives for electric vehicles. Diess said Germany was nonetheless on the right track, with electric car sales "performing really well".
