Shares in Uber closed out at $27.83 on March 30, well down on the $41 mark they had reached just prior to the stock market crash triggered by the coronavirus pandemic. As of the writing of this article, Tesla’s shares were sitting at $30.46. That is well down on the $45 that the shares started at when Uber went public in May 2019.

Toyota has had a keen interest in Uber for quite some time. In August 2018, the car manufacturer invested $500 million in Uber to jointly work on the development of self-driving vehicles with a plan for Uber to integrate Toyota’s Guardian driver assist technology with its self-driving system. Future Car reports that in 2016, Toyota also invested an undisclosed sum in Uber to partner on a car-leasing program for Uber drivers.

Uber had been aggressively testing and developing self-driving technologies prior to a crash in Tempe, Arizona on March 2018 involving one of its autonomous vehicles. The ride-hailing company resumed testing of its vehicles nine months after the crash but on a greatly reduced scale.
