Didi by the numbers: Ride-hailing firm covered more miles in 2018 than five Earth-to-Neptune round-trips

Didi users travelled 48.8 billion kilometres in 2018, equivalent to about five round trips from Earth to Neptune.

China's largest ride-hailing services operator Didi Chuxing, which forced Uber Technologies out of the country, had a bumpy journey in 2018, as the company’s expansion plans were checked by passenger-death scandals and safety concerns.

As one of the world's most well-funded startups, Didi was riding high until two passengers were killed while using its service within the space of three months, putting the brakes on the unicorn’s growth and shining a spotlight on the wider on-demand transport industry in China.
