To be honest, I'm more concerned that people will learn how to hack self driving cars more easily. I'm not familiar enough with this stuff but I'm more worried that someone could hack another person's car and take control of their vehicle. Or someone spreading a virus through vehicles. As I said, I'm not very knowledgeable on this subject but if self driving cars could be hacked. Then I could see it being a new favorite weapon for terrorists.
Also would this significantly effect the jobs market? Truck drivers, delivery drivers, Cabs, Uber, etc. I imagine a lot of those jobs will get hit hard especially Cabs, Uber, Lyft, etc.
Not to be a debbie downer as I'd be the first person in line to get a self driving car. However, the effects would be significant and not to be taken lightly either.
