The problem is less the limits on itself, but more that they might be reached "surprisingly". E.g. sudden dust storm on the highway in Germany where dust and/or sand storms on itself are a rarity (also this is something humans are bad at coping with themself, as given example caused a accident with multiple dead people). Less unusual but still realistic example: Sudden extreme heavy rain (I had that once, the car I was driving in was old needed new windows and I wasn't able to see anything at all. The only reason I didn't cause a crash is because I knew the road I was driving on very very well). Or sudden fog. Humans just tend to be better at handling such potential fatal unexpected situations, e.g. because they have a good memory of the road and contextual thinking in ways which are hard to explicitly train a robot in. So they kinda need to find ways to still handle things well in such situations and "just stopping" isn't an option as this might endanger people around you (and yourself).
