The CEO of one of the world's largest automakers spent last week encouraging people to get around on two wheels instead of four.
Volkswagen Group's Herbert Diess said bicycles are an important part of ensuring that cars have a future in dense cities.
"Biking is fun, healthy and good for the environment," Diess wrote on Twitter. "Overcrowded urban centers will only accept cars — even with zero emissions — if bikes have enough room in the mobility mix."
Diess also used LinkedIn to promote a project aimed at getting VW factory employees in Wolfsburg, Germany, to bike to work.
"Do you want to sell cars or bikes?" one commenter retorted, though others expressed support for the initiative.
