This illustrates that if drivers feel less safe then they drive more safely and pay attention more. It is one of motivations for removing all signage so drivers feel less safe permamently. http://thecityfix.com/blog/naked-streets-without-traffic-lig... https://www.theguardian.com/commentisfree/2016/feb/04/remova...

I think that removing all signage would have a similar effect: short-term reduction in accidents, but then a rebound (or worse) once drivers adapt.

Okay, fine. Then we ramp it up by employing hundreds of clowns to hide in the bushes on the side of the road and jump out when the driver least expects it.

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 whi…

Any large bright signs at night should ideally restrict themselves to orange/red, and be of brightness appropriate to dark-adapted eyes. Even a lot of recent traffic signals have blue–green “go” lamps which are excessively bright. The new LED car headlights (especially seen on luxury cars) are universally awful: distracting, blinding, and wreck your eyes’ adaptation. When they show up on a tall vehicle like an SUV it…

Headlight brightness is somewhat of a balance, between blinding oncoming traffic and not being able to see far enough ahead. Dark adaptation has its limits.

(AFAIK it's actually HID lights which make up most of the ridiculously bright headlight market.)

Having bright blue headlamps makes it harder to see into the shadows even for the car’s driver, because it causes the eyes to be less dark-adapted. Older halogen lamps work better in practice. The newer LED lamps only sound better in marketing materials, and based on junk metrics created by the industry itself.

Hah. I say we skip the middlemen and deliver electric shocks directly to the driver's hands through the steering wheel at random intervals.

Replace all the signs once the rebound begins, and you’ll re-befuddle everyone. Take the signs back down once that rebound hits, and repeat.

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.

I mean given where you would expect the shadows of floating blocks to be when illuminated from your headlights.

The shadows would appear wrong when lit by headlights, which might be a little bit disorienting. The shadows are rendered as if a light was high overhead.

I think the illusion would still work fine, but feel subtly "wrong" to the driver. Probably good enough to get people to slow down, though.

It's all smart and clever until someone gets distracted, slams the breaks, gets rear-ended and breaks the neck.

The speed limit is 18mph. No neck breaking can happen at that speed.

That's faster than you are moving when you are executed by hanging (about 17 mph for long drop, 13 mph for standard drop), so I would not dismiss the possibility out of hand.

Why weren't a series of speed bumps suitable?

Plowing in Winter perhaps?

Yep, plowing and speed bumps don't mix. My workplace bought removable speed bumps. At the first snow, they maintenance folks unscrew the speed bumps from the roads / parking lot that are owned by the college. When the snow melts, they put back the speed bumps. Also, speed bumps with ice accumulations are just nasty.
