Ola is planning to build the world's largest electric scooter plant on a 500-acre vacant plot in Bengaluru's outskirts, Bloomberg reported. Ola Electric Mobility hopes to make 1 crore vehicles annually or 15% of world's e-scooters by the summer of 2022. That would be one scooter rolling out every two seconds after the $330-million plant expands next year, Bloomberg added.
