technically correct title (the best kind!) - but clickbaity because everyone wants to see a serious test of self-driving on snow-covered, icy roads, ideally with actually blinding, falling snow - at night. This is, if anything, even easier than a non-snowy drive because of the high contrast between the completely clear road and the snow-dusted sidewalks.

The dream that the developers, the media, and many of us share is to change the world by making driving a thing people do not do. Matching a human driver in the most treacherous conditions is a major, and unmet milestone. This is a misleading post.

I want to see AI trained to drive like people in Russia: https://i.imgur.com/wDhO25d.gif

No, please, we need AI, which will make road a bit less dangerous. We have such an anecdote: when you cross the road in Russia, you have to look not only left and right, but also up.

If you look closely the car is driving in circles. They revisit the same roads many times in just a few block radius.

I also noticed that it was driving 25... I assumed that was 25 km/hr, which is pretty darned slow (15mph) even on snowy city streets. However, it could be that they're running the car in US mph instead?

Earlier quoted context omitted.

Volvo has proposed driving magnetized nails into pavements in Sweden as lane markers. Not only are these useful for self-driving cars, they're good for snowplow guidance.

How often would the magnets need to be replaced?

As often as the asphalt topping.

I don't think CV ever will account for that. I always have thought the answer is going to be somewhere between great technology, and infrastructure to support it. We need "smart" roads.

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…

There's some interesting recent work at (IIRC) MIT using ground-penetrating radar techniques to image subsurface features of the roadbed in real time, as the car drives over them. Rocks, rebar, and such are almost completely weather-independent (short of torrential rains that wash out the road itself), and they don't change significantly over time.

Have you ever seen someone driving in snow anywhere south of Pennsylvania in the US?

This tech, as-is, could probably save millions in damage on minor or one-car accidents in snowy aftermath. Even if it snows once or twice a year, somehow everyone forgets how to drive safely in the snow and Every.Single.Time there is snow the world just stops.

Unrelated to this video, I was impressed with my Subaru EyeSight performance in a whiteout rainstorm. I could tell what was going on - barely, with the wipers at full tilt - and my auto-cruise worked without a hitch at > 50MPH for several minutes straight. It's definitely hit-or-miss though, since sometimes it gets confused on a bright overcast day at 25MPH.

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...

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?
