Most likely, every self-driving car company will send drivers down every road in the country, recording everything they see. Then they'll have human labellers figure out any junctions where the road markings are ambiguous.
They've had sat nav maps covering every road for decades, and the likes of Google Street View, so to have a detailed map of every junction is totally possible.
In that case I hope they're prepared to work with local authorities to immediately update the map every time road layouts change, temporarily or permanently. Google Maps gets lane guidance wrong very often in my experience, so that doesn't exactly fill me with confidence.
I kind of assumed that already happened. Does it not? Is anyone pushing for it?
Honestly it seems like it ought to be federal law by now that municipalities need to notify a designated centralized service of all road/lane/sign/etc. changes in a standardized format, that all digital mapping providers can ingest from.
Is this not a thing? If not, is anyone lobbying for it? Is there opposition?
Road layout can change daily, sometimes multiple times per day. Sometimes in a second, like when a tree falls on a lane and now you have to reroute on the oncoming lane for some distance, etc.
Coordinating roadwork is challenging in most places, I think. Over here, it's apparently cheaper to open up a road multiple times in a year, rather than coordinating all the different parties that need underground access in the foreseeable future.

Why not just anyone and make that data openly avaiable?
