Driverless vehicles will not be operating on public roads at any point during our or our children's lifetimes.
I don't doubt that the technology might soon exist but we are a long way from the point where the general public would allow them.
Here in hoping my current car last long enough for me to buy a driverless. Car next. I would be happy with it just being able to handle interstate roads which some companies say is just a few years away.
The public may not have much choice in the matter as the technology is already creeping into cars now.
