I hope that this is not the normal speed of the video. It looks a dangerous situation for pedestrians to me, specially in urban roads and streets.

Canadian perspective: This is very clear. Much more challenging is something like a multi-lane highway where the road markings have completely disappeared under snow. I'll be impressed when it can drive from Hope into the BC interior in winter in conditions that a human driver can handle with winter tires and possibly studs, but no need for chains. https://www.google.com/search?client=ubuntu&channel=fs&q=coq...
Accurate GPS and a well mapped area can give the car a precise road lane when snow is present.
That's assuming a very accurate GPS in very good conditions. You also need to be sure that there aren't any road works that would temporarily change the lines. Seems a bit risky to commit 100% to the GPS for that.

There's a 4x indicator in the top right corner.

Oh man I've driven through canada to blue mountain during a blizzard. That was scary. I really have to wonder how computer vision will account for that. Or similarly torrential downpours here in the Tropics.
Perhaps better. LIDAR can distinguish between clear, solid and semi-clear (snow and slush).
Radar doesent care about water (at street distances).

#85Why do people think that driving on snow/ice is going to be a challenge? Compared to recognizing the cars, lights, pedestrians, and their intention, that's pretty straightforward.
Because it's harder to orientate when you can't see the street markings, see the street signs, when your cameras are snowed over. If you tried parking a new BMW after a snow storm and looked out the rear camera you know what I mean. Basically they have to do all they normally do but just the equipment they need to keep cameras and lidars without snow either costs an extra fortune, OR the passengers will have to start…

Sorry if I'm being ignorant (where I live, below 20°C is really cold weather, and the lowest it gets is around 10°C, which I don't recall ever seeing), but wouldn't heaters be enough?

#86I'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.

In fact this scenario is easier than no snow, since road edges are so clearly defined
Then it should be easy to show a self-driving car working in those conditions. Somehow, despite this argument coming up in virtually every discussion of this kind, nobody's done it yet.

I'd be impressed if I see a self-driving car making a left turn in a crowded junction without a specific left-turn signal at LA. The only way to turn left in such roads is to make an illegal turn after the signal just becomes red. I wonder how the self-driving car would do in such a situation.
Equally impressive would be four self driving cars turning left (in right-hand traffic) at equal priority intersection. At least in my country the rules are muddy in this case and no car has explicit priority. The most general "priority in right" loops around and cars should be stuck there indefinitely :)
I like to imagine to avoid such situations there would some kind of control on the dash that allows a stalemate to be overridden (not the steering wheel :P). It would be great if it were a "give way" button rather than a "I'm going now" button.

Ultimately I think it'll have to be smart highways. You could embed a coded marker in the centre of each lane which the car can pick up using RF (e.g. an induction loop). This plus other constraints like GPS, visual-inertial odometry, etc should be enough to localise and remain safely within a lane boundary even if it's invisible. This would work fine through a layer of snow - some of the more expensive ski jackets h…
It's hard to see how we could get from where we are right now, infrastructure-wise, to there, at least here in the US. We can barely keep our roads driveable in some places, much less modernized with the latest in smart beacons and such.
Yes. Smooth, flat, pothole free tarmac would be nice.

#89The hardest human equivalent in New England in my youth, was a 4 way stop at the peak of a steep hill. Would have loved to seen this scenario with the self driving car.

#90I like how the car alows down a lot when squeezing through tight gaps
