I wonder how well it would work in the dark.

Well, if you can’t see the road, there’s a problem in and of itself. Assuming good headlights, which I think you’d want in Iceland, and assuming modern road paints, it should work. If not, just stick a road light over it.

Yes but how well would the illusion work in headlights?

It should work, modern headlights are no joke, but I admit that I’m not sure. If you have enough light to perceive a broad range of colors it should work.

There is an analogy here to the slippery-slope of attention-getting ads on the Internet. Once upon a time an ad was just a static (not even animated) banner of a certain size and shape. 468x60 was one of the earliest, IIRC. Advertisers invented new formats ("skyscrapers", "xl-leaderboards", "300x250", and so on), and also they got animated, and then they started expanding outside their areas, and so on; each new ad t…

When Sweden changed driving side, that is exactly what happened.

"The relatively smooth changeover saw a reduction in the number of accidents. On the day of the change, only 157 minor accidents were reported, of which only 32 involved personal injuries, with only a handful serious. On the Monday following Dagen H, there were 125 reported traffic accidents, compared to a range of 130 to 198 for previous Mondays, none of them fatal. Experts suggested that changing to driving on the right reduced accidents while overtaking, as people already drove left-hand drive vehicles, thereby having a better view of the road ahead; additionally, the change made a marked surge in perceived risk that exceeded the target level and thus was followed by very cautious behavior that caused a major decrease in road fatalities. Indeed, fatal car-to-car and car-to-pedestrian accidents dropped sharply as a result, and the number of motor insurance claims went down by 40%.

These initial improvements did not last, however. The number of motor insurance claims returned to 'normal' over the next six weeks and, by 1969, the accident rates were back to the levels seen before the change." https://en.wikipedia.org/wiki/Dagen_H

Why Iceland more than other places?

Strongly agree with everything here. Just wanted to add that getting people accustomed to this has unintended consequences as well. Say you grow up in a place where this is the norm. Then you go to some place where this hasn’t caught on yet.

You’ve been trained to look out for these obvious things and therefore pay less attention in general. You are now a more dangerous driver outside of this environment and possibly even within it.

Some things are not supposed to be “easy”. When you’re driving around in a heavy metal object capable of killing or at least injuring other pepple, you are supposed to be actively paying full attention to all of your surroundings at all times.

Making things stick out like this and tricking people into freaking out a little bit trains people to pay less attention in the long run.

It’s the same thing you were saying about bigger and more obnoxious ads. I’m just making the connection explicit.

On a route through Germany that I take with some regularity there is a passage where they have been working on the road for years now. At the entrance to the roadworks are two giant flashing triangles, those work well in full sunlight but at night I have to close my eyes or look away while passing near them or I'll be totally nightblind for the next couple of kilometers which is not a very good thing to deal with while in a construction zone. Extremely silly that those things do not decrease their brightness at night.

They're in range of the polar night, and headlights are mandatory to be on at all times. It can be a dark place.

These 3d perspective drawings are much less convincing in real life than they are in images, because in real life we have depth perception and our viewpoint is constantly moving. This only looks good from that exact viewpoint.

CAVE style VR suffers from the same problem if you don't want to use stereoscopic shutter glasses. You can track one user's head position and update the renderer's camera accordingly, but with multiple users you can't do that without shutter glasses.

Even with shutter glasses, I'd think there must be some limit on how many users you could have at once without irritating flickering; with 3 users and six different perspectives to render, both displays on an individual user's glasses would be opaque 2/3 of the time, and each eye would see an image for 1/6 of every unit time.
