Everything is in constant flux, even roads (-&gt; constructions, putholes, snow etc).,(reply>), @machelvet i'm sure the solution includes multiple approaches, combinations of previous data from that area, estimating where to go based on the edges of the road or other indicators, looking at tyre marks and the cars ahead etc.<br>that's pretty much what we do as well, i think autopilot will end up using similar techniques when it has to guess.<br><br><br>I don't think people working on this consider the lack of markings or these sort of scenarios to be the number one challenge like the general public seems to think, that's why they don't talk about it all that much.,(reply>), @Jeremiah John No, no, I don't think he's a moron. On the contrary, I enjoyed the video and his insight very much. It was amazing.<br>In context, he distinguished between ballistic and stationary things and that got me thinking. Are roads really fixed and given? Which led to the examples. I could even ad earthquakes or flooding.<br>And I actually do think, that the AP is working with a flexible road layout since the newer versions try to avoid big puddles at the roadside. Or think of snow, when slowly all the white markings disappear and the highway turns into a white painted sheet with no markings.<br>It was fascinating to listen to him and if I could have asked a question, I would have loved if he had the chance to talk about a well marked road turning into a single color white sheet with no edges. How does the AP solve that? - I mean, it must be incredibly difficult to keep the car and the people in it safe in those conditions.,(reply>), that's not what he said, he said you can map everything thoroughly as in the computer can model what it's looking at, he didn't claim everything stays literally exactly the same come on he's not a moron.
