For now. Anyone who thinks that eliminating drivers isn't the end goal of this (or that we lack the ingenuity to do it) is fooling themselves. Think about it. If you replace your fleet of regular trucks with driverless ones, you suddenly don't have to pay all those drivers $50k a year (or whatever it pays now), and your trucks are twice as productive because they can operate 24 hours a day since there's no driver to get tired.
Mind you, I'm not advocating that we halt technological progress, but we're coming up on a time when there just aren't going to be enough jobs to go around, and the economy is going to have to adjust for that in a way that rewards people who work but doesn't starve people who want to work but can't find jobs.
