Re: In perspective, Galileo isn't important
"You need far better accuracy than 1 metre if you're going to have self-driving cars trundling around."
Wrong.
The accuracy needed for autonomous vehicles just needs to know where you are and what lane you are in. If lane centers are 3 m apart, then 1 m accuracy will do that quite nicely.
The precision lane-keeping, vehicle avoidance, etc, uses radar, lidar, vision systems, and sonar. That's why these cars often want painted line markers.
My GPS is quite reliable - much more so than my previous unit - at determining which lane with an accuracy that is never claimed to be better than 3 or 4 meters.
