Automakers Toyota and Volvo, could feel the impact of a crash on March 18 in which a pedestrian was struck and killed by a self-driving vehicle belonging to Uber in Tempe, Ariz.

Although details on the incident remain scant, the aftermath is raising questions about the validity and safety of autonomous vehicles. According to an article posted by the Detroit News, Volvo, which has supplied SUVs to Uber for use in its self-driving tests (using Uber’s own software and sensors), said in a statement that Uber is cooperating with local authorities following the crash.

Toyota, which has been developing a strategy to work with Uber in AV testing recently stated that it had not made a firm decision on whether to purchase Uber’s AV software. This follows from a news announcement at this year’s Consumer Electronic Show (CES) in January, where Toyota announced plans to develop electrically propelled AVs in partnership with tech giants Uber and Amazon.
