It seems to improve safety. In Bulgaria it's mandatory since a few weeks I belief....

There is scientific evidence daytime lights on reduce accidents as it increases awareness of other vehicles in the peripheral vision of drivers.

I agree on their usefulness. Even in bright daylight a vehicle with headlights (or, way better, DRLs) on is much easier and faster to recognize.

The front lights are two points of concentrated light (much stronger than environmental lighting) placed in a fixed position -the corners of the vehicles- and this make it quicker to understand not only its position, but mainly its relative speed.
That happens because calculating a variable distance in perspective from our P.O.V. to the object is a hard task, while if you look at the lights you have to calculate if they are getting closer or more distant to each other.

It gives its best advantage especially in rear mirrors view.

What is more, if sunlight is very bright you have a high contrast between sunny areas and shadowed spots (as under some trees or an overpass), where objects can results harder to see than it would seem. DRLs help in this case, too.

The downside is that it obscures motorcyclists, especially during the summer when there are many of them.

You forgot to mention that cyclists and pedestrians suffer from the fact that they are far less 'visible' with daytime vehicle lights on. I've experienced the nonsense of the measurement in Hungary this year. So let us hope the disease doesn't spread any further...

I can tell the Dutch from miles away in France. Always spontaneously their headlights on in the name of the Father, the Son and Safety.

N50 Kampen

This is an aerial photo of the N50 near Kampen. On the left is the new Hanze Railway Line, where services will begin in december, on the right is the reconstructed N50.

Notice both the railway and the N50 are going over viaducts that cross nothing. A bypass of the IJssel River is planned here. Because there are no floodplains near Kampen, the river can go nowhere but up, so they will construct this bypass in the future to prevent flooding in Kampen and upstream. Notice how the N50 is already designed with space for a 2x2 motorway.

Some Dutch highway pics

A10, Coentunnel Amsterdam:





A2 near Utrecht:

The bulb at right contains the display of a luxury car garage, the first days after the opening many people drove slowly there to see the cars on display and caused traffic problems!

I like that last photo. It's A2 at the Nieuwegein exit. You can only take a photo in that direction from a bus or high van. There is a cycle path on the other side of the viaduct.

Pedestrians are reported to be the ones who benefit most from daytime lights on, especially in term of judging the speed of vehicles.

Lots of research and studies on that.

Remember that Postbus 51 commercial* in the 1990s? It had a split screen. On top there was a car approaching without the headlights switched on, below a car with the headlights switched on. A voice-over made it very clear it was a good idea to always switch on your headlights.

*Postbus 51 = public television announcement, for non Dutch speakers.

The worst part is that some European drivers glare you with their front fog lights during the daytime. From these pictures, drivers seem to just have their headlights switched on.

That car garage went bankrupt, didn't it?

Depends where you are. In the northern parts it's a lot more common.

Why does A2-West have such a big sign, with a lot of empty space, in comparison to the A2-Zuid sign

The widening of the A15 near Barendrecht, south of Rotterdam. Pictures are taken from the 'green' noise barrier between Barendrecht and the A15. A pedestrian path is being built om that 'dyke', so now everyone can watch the widening very closely
