It might begin very soon

What happens when the road isn't where it is supposed to be? Like in a construction zone where the road was moved over a few feet. I know. The car runs into the guard rail. Seen it happen.

Without local augmentation, which is the vast majority of the country, GPS is not accurate to a few feet. Even if it was there are things other than guard rails that move so all self driving cars have methods of detecting these things. Tesla has had a few cases where they failed to properly interpret stationary objects but there are far more cases where they have successfully driven on unmapped roads, just relying on their sensors to find the way.

Tesla and the competition are addressing issues as they come up and are making a lot of progress. My understand is that Tesla has done at least two complete re-writes of their software to address deficiencies in detection. These re-writes have moved them away from being data driven to operating more like humans and using live, real time observations for determining the best path. Unlike humans, they do have radar and other methods of detecting things that cannot be detected visually for even more complete information.

Even though the number of Teslas on the road is increasing rapidly I have not been hearing about FSD failures nearly as often as I used to. It seems to me that they are steadily getting better.
