It's still unclear to what degree Uber's vehicle was responsible for the tragedy. Tempe's police chief has said he doesn't believe Uber is at fault, but the department isn't responsible for determining the fault in any crash.

The incident came not long after Toyota and Uber had formed a partnership, and just days after a report claiming that Uber was hoping to sell its self-driving tech to Toyota. This isn't likely to put deals in jeopardy, but it may lead to more caution from both companies as they minimize the chances of a repeat incident.
