Waymo is expanding the coverage of its driverless taxis in San Francisco and Phoenix. Driverless cars seem to be an area that combines actual technical progress over the last 10-15 years with still a fair bit of hype, making it hard to know how far along the technology really is from a mass-market perspecitve.
It might be a long-time until we have driverless cars everywhere, but driverless cars seem destined to be me in more and more places over the next few years. The time it will take to have driverless cars everywhere will likely be as much about regulation as it will be about technology.
