Self driving cars on the Highway are on the way, if the pun is excused. There are quite a lot of experiments and development. There is an EU program, etc. Sure, to get them on the roads (and integrate their systems with highways etc) will certainly take at least another decade.
The point is, the subject is not a joke, as the article insinuated.
That said, I'd not trust Kurzweil's claims on e.g. economics or cancer research. I might give some credibility to experts in those areas.
