The tech is still developing. We may be in a bit of a hype bubble, but it is as real and clear as it has ever been. I think even as the tech advances rapidly, public acceptance will be way further out than 5, 10 or 15 years. I would venture to say self-driving cars and truck fleets being normalized is 30 years away and in no way because of the tech, but due to all the red tape and public debate that will encase the issue.
If you think all truck drivers are going to be displaced in 5 or even 10 years, you may be living in an HN bubble. Sure jobs will be automated away, but this is going to take more time than lots of people think. For instance, one article like this could delay acceptance for months or years, in my opinion.
