> When Power Loom was introduced, it was often a centre of vandalism because it was destroying jobs.

You just gave a very good example right there of a potential for new jobs but you overlooked it:

Employing former truckers as guards for self-driving truckers to protect them and their cargo from vandals and protesters.

Until self-driving vehicles also become self-defending, humans will still have to sit in the automatic trucks. They'll still need places to grab food from along the way, and so on.
