Actual “self driving” cars being anything more than a tedious novelty will follow roughly about the same timeline as self driving trains - my kids and grandchildren can look forward to it maybe happening before their retirement!
On a serious note, far from there being a need to ‘free up’ all those hours of human labour spent driving vehicles for a living, driving employs a huge number of people and provides a mostly unskilled sector of the population with something approaching a reasonable, respectable living. Bottom shelf courier cowboys aside, employment as a bus, lorry or taxi driver for many folk who do it is a better proposition than a lot of the alternatives. There are always the cries of “they said that when the mills closed” etc, but in an age where the steady march is only ever closer to squeezing more humans out of the workplace, there really does need to be pause for thought about the pitfalls of mass autonomy. What will replace all these jobs? The warehouses and factories are all increasingly full of robots, the high street is in its death throes, and there are only so many branches of the Coop that need staffing… “Retraining is the answer” - but as what, and at whose expense?! We can’t all be hairdressers or social workers.
Only the blind could fail to notice that we already have a sizeable chunk of society who are utterly disenfranchised without meaningful employment or a sense of worth or purpose, and the outcome is not good. Recent mass rioting was a pretty decent red flag, in case anybody really hadn’t noticed. Taking away solid employment when there really is precious little in the way of quality alternative seems a deeply misguided path.
