I'd be curious to understand why the they think the technology would work in fog. The article suggests it does, but the science behind how that worked wasn't explained (or I didn't get it). Does anyone understand this? The problem with fog as I understand it is that it defuses light, washing out vision. My understanding is that Lidar does not bounce off fog, or at least to the same degree. Is my understanding there correct?
