I want to know what they were thinking. "Alright, 10cm of snow ... send out the bots that are completely unfit for these conditions!"

While questionable considering the location, of course it's fine to not design them to work in snow. What baffles me is that they didn't design them to work in snow and sent them into the snow.

Considering that it's a lot of them in a bunch I can imagine that the bots had just started from their garage. Maybe this was some internal test?

I can't imagine somebody consciously decided to let these things go through snow and operate normally. And surely there's that amount of human oversight ...
