It’s unclear as of now what exactly happened. The test driver, Rafaela Vasquez, has not been charged in the incident.
But it’s thrown the role of test drivers into the spotlight.

Why would a self-driving car have a human behind the wheel?
Automakers, tech companies and startups are all developing self-driving cars, but the tech is far from perfect. Companies hire human test drivers to sit behind the wheel of self-driving vehicles and take over when necessary, say, if a car’s sensors fail to recognize a bicyclist, pedestrian or other vehicle — or if the software system crashes.
far from perfect: 远不及完美 （这个词组在PTE写作中也可以使用，当讨论一个观点虽然好但是仍有弊端的时候可以用 something indeed has undeniable merits but it is far from perfect）
pedestrian: 行人 （这个词要注意读音）
