Volkswagen’s sports car maker Porsche could develop a flying passenger vehicle to compete with rivals in a possible market for urban air taxis and ride-sharing services, Porsche sales chief Detlev von Platen told a German magazine, Reuters reported.

“That would really make sense. If I drive from (the Porsche plant in) Zuffenhausen to Stuttgart airport, I need at least half an hour, if I’m lucky. Flying would take only three and a half minutes,” Automobilwoche quoted von Platen as saying.

Porsche would join a raft of companies working on designs for flying cars in anticipation of a shift in the transport market away from conventional cars to self-driving vehicles shared via ride-hailing apps.
