Nothing except time and money, but that's a lot of people. Even occurring over a decade or more it's going to cause the wages of a lot of those trades to plummet.
The specific instance here was drivers, who in this hypothetical, will be outcompeted by self driving cars, and and naturally find themselves with more time on their hands whether they want it or not.
As to money, there are a number of trades you can learn without spending money. And there are also jobs where you get on-the-job training.
I'm not saying it won't be a problem for these people, but eventually, most if not all will adjust to the new situation and find themselves in a new job.
