San Francisco is building its new Central Subway -- an underground light rail line. Ground was broken in 2010 but due to delays it will not open until 2021. This line will finally make the Caltrain commuter rail (which otherwise dumps passengers into an industrial zone far from where most of them wish to go) more useful, and offer travel not slowed by SF's terrible central district congestion.

California announced that come April, it will be legal to operate robocars with no safety driver inside. There will need to be a remote operator, monitoring the vehicle at all times during testing.

Waymo has applied for, and been granted, a licence to operate as a "Transportation Network Company" (fancy name for app-summoned taxi like Uber) in Arizona. This has been expected for some time, and shows they are continuing their plan to open up their pilot service in Phoenix to the public.

Every 2 years I watch the Olympics and publish notes on the games, or in particular the coverage. Each time the technology has changed and that alters the coverage.

This year the big change is much more extensive and refined availability of streaming coverage. Since I desire to "cut the cord" and have no cable or satellite, this has become more important. Unfortunately the story is not all good.
