The new ridesharing economy continues to beat expectations as ABI Research forecasts global bookings to exceed US$100bn by 2020 and $300bn by 2030.

But the transportation industry may be in need of a reality check. Many car OEMs are now aiming to gain back control of the future automotive landscape through advancements in driverless car technology. This will enable driverless taxis to overpower ridesharing in the long-term.

Dominique Bonte, managing director and vice president at ABI Research said: "There is no doubt that the ridesharing ecosystem will mature, with Chinese ride-hailing service Didi Chuxing merging operations with Uber in the region and Uber reaching an incredible milestone of 2bn rides this past June. Yet, however promising this new car sharing economy looks, its growth will eventually slow."

Big brands and niche startups like Opel's CarUnity and carpooling operations like BlaBlaCar and Scoop Technologies, in which BMW i Ventures recently invested, are currently thriving. But ABI Research finds ridesharing growth will slow as it becomes more challenging to recruit users.

Its business model of aggressive marketing and subsidised driver recruitment resulting in huge losses, as well as fundamental cost structure limitations, will prevent ridesharing from scaling into a mainstream use case and, as a result, fail to lead to a significant decline in car ownership.

To adapt to the changing competitive landscape, many car OEMs recently announced partnerships and/or investments in ridesharing brands, as evident with Tesla's Musk and GM's and Toyota's intentions to partner with and invest in Lyft and Uber, respectively. Some OEMs, like Ford and Tesla, announced plans to set up their own driverless taxi fleets, both to compete with ridesharing services like Uber and allow driverless car owners to engage in community sharing.

"Unsurprisingly, Didi Chuxing and Uber are also exploring driverless taxis," said Bonte. "Driverless technology will allow the car sharing paradigm to maintain growth levels beyond 2025. Other initiatives to support this economy include driverless shuttle and taxi trials by Delphi, Navya, and nuTonomy in Singapore and Japan's plan to deploy driverless robot taxis during the 2020 Tokyo Olympics."
