It's also worth noting that if we get a major switch to self-driving cars, that won't create a new industry but rather diminish one - a big hypothetical benefit of a self-driving-car world is that much less cars would be needed; as most current cars are idle most of the time and even in peak driving hours, so a societal switch to "self driving cars on demand" services would mean that we would need much less cars than today.

Which is great for the planet, but not so great for jobs in car manufacturing industry, at least in the long run.
