DAVOS: Formula One world champion Nico Rosberg said on Friday that there was more to life than driving round in circles and hinted that he was considering investing in electric cars after his shock retirement. The German, who announced his exit in December just five days after winning the world title at the age of 31, said that his plans included charity work and spending a lot more time with his wife and daughter. “Life has more to offer than driving round in circles,” he told an audience at the World Economic Forum in the Swiss ski resort of Davos, where business leaders, politicians and celebrity philanthropists have been gathered this week.
