I think it's 25km/h but those streets are pretty narrow and filled with pedestrians. Normal speed limits on those streets is 30km/h so driving between 20 and 30 seems right.
The video should be watched at 0.25 speed to get the realistic impression.
If anyone was going to focus on making sure their self-driving car could drive in snow, it'd be the Russians. Mind you, self-driving when snow has coated all your landmarks is definitely impressive, but the title made me think it'd be driving in snow . Which it isn't. The roads are, what we'd call in Chicago, "clear". The car is not driving in/on snow or ice in this scenario, which is something I do regularly every w…
Yeah, as a New Englander, that's not what I call driving after a heavy snowfall.
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.
There's a 4x indicator in the top right corner.
The video deserves a second view, with a proper BSO :-)
If that is after a heavy snowfall they need to test in Canada.
Maybe it's also after cleaning streets right after heavy snowfall? :) For snow-covered roads we'll have to wait for reports from, say, Chelyabinsk. Or Tomsk, or Novosibirsk...
So this video features a self-driving car developed by Yandex. Does someone have insight into why so many big tech companies seem to all be in agreement that developing self-driving cars is an area they need to be pursuing? Is it mostly everyone looking at what Google is doing and replicating that? Or is it the getting swept up by the Uber hype? Or is working on self-driving car software just such a natural extension…

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.
Ideally, isn't the point to have only autonomous vehicles and these situations become obsolete?

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.
(GP: That's actually easy: random exponential binary backoff. It works for other domains quite well.)

How often would the magnets need to be replaced?
As often as the asphalt topping.
Plus there's also no incentive for anyone to waylay the smart road off the physical road, because there are no evil people (i.e. with motives that are incompatible with the vehicle's survival).

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.
The idea would to put the smart tech in the car. What's going at the roadside could be made very cheaply and integrated into existing features without needing to rip up the entire road.
Other countries have toll highways which are well maintained, that's another option for installation.
I don't see this happening in rural/country lanes, the cost would be obscene (but again, we do liberally use reflectors in the UK). I also don't see this as a panacea, it would simply be a backup in horrendous weather.

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.
"Works great near my house, might accidentally kill you if you try to ride it outside the happy path" is somewhat underwhelming.
