Star Wars is a futuristic fantasy story.
I thought it was set a long time ago (in a galaxy far, far away).
The car was basically equipped with a stay-in-lane and slow-down-if-you-approach-the-car-in-front-of-you kind of system, which is not an autonomous vehicle, nor can you take your eyes off the road. At best it reacts a bit faster if someone in front of you hits the brakes. Google did a talk on this and said in their tests, as soon as a car seems to be working by itself, drivers stopped paying attention to the road, so half-way-autonomous is a bad idea. People don't want to pay attention and they won't if the car seems to be doing a good enough job.
Only a fully autonomous car will be good enough.
I work in a factory and stuff is occasionally installed wrong or fails in such a way that stuff breaks, sometimes by melting or having smoke come out of it. Nobody was injured and the result of the problem didn't cascade and create other problems (at least nothing serious apparently) which means it's not a huge deal. Replace the cables, align the mirrors properly this time, update the process for mirror alignment and verification and get on with life.
I seriously wonder what kind of sheltered life people must be living to not have experienced stuff breaking down and having to repair it. Have you not owned a car? A washing machine or dishwasher? A computer with a hard drive? I've twice been in the vicinity of electrical transformers that exploded rather spectacularly, both of which due to high winds. They're up on a pole so nobody got hurt. They were fixed within a matter of hours. Seriously, stuff breaks down, usually for quite run-of-the-mill reasons, often due to human error, and it has to be fixed. Why the shock and mock outrage?
