More specifically, Uber said this round of investment will finance more research and development of the hardware needed for autonomous cars, as well as helping start mass production and commercialization of self-driving ridesharing vehicles. Uber has made no secret of the fact it wants to launch self-driving services, eventually cutting today's human drivers out of the loop.

Toyota and Uber have had a connection for some time, with the automaker investing $500 million in Uber back in 2018. At the time, the stated goal was to build self-driving Toyota Sienna minivans that could be put into commercial use for ride-sharing by 2021. The vans would use Uber ATG's self-driving tech along with Toyota's Guardian active-safety technology.
