All those previous things you mentioned were technologies that greatly increased productivity - that is, they produced greatly more output with less input, so they had a significant effect of reducing cost of pretty much everything. This meant the temporary effects of job transitions were not as harsh, because there was an environment of increased standard of living.
We aren't in a world like that any more - technology is not passing the results of increased productivity on to higher standards of living at the same rate to the people whose jobs got displaced* so the transient effect of disruptive technology is going to be more severe.
*This is important - yes, people in "third world" countries are having their standards of living increased rapidly, but this is now at the expense of standard of living of people in the highly-developed nations. We just got out of a strange century or so where people were gaining standard of living without reducing others' standards of living.
The potential for productivity increases for automated personal transport is low - we are so far along the curve of diminishing returns that it is costing society significant amounts for small gains in this industry, and when it comes to automotive safety, we are actually now probably spending more as a society (at least in the US) to eliminate one accident than that accident itself - even a fatal one - would cost society in terms of productivity.
