I'm sorry - this isn't a "heavy snowfall" in Moscow. It's just barely a dusting. That isn't even an inch of accumulation. Being able to self-drive when there is black pavement to be seen isn't impressive in the least. Show me a self-driving car functioning in white-out conditions (which is what Moscow faces on a regular basis, as does a large portion of the US) and I'll be impressed.

Is what it looked like ~two weeks ago. Show me your self-driving car in THAT.
