Is any government anywhere 'always wise'?
Not at all. But when it comes to building roads, the Dutch government appears to be extremely unwise.
It's a small country, much of which has been reclaimed expensively and with great effort from the sea. But they spray tarmac around with gay abandon as if they had as much land as the US. I can understand, and accept, the extra width given to just about every road other than motorways for cyclists and moped riders (although they seem very lightly used outside of the towns, and there's far too much block paving).
But the Dutch attitude to road junctions seems to be to add an extra lane if in doubt. The motorway around Rotterdam was horrible - jumping from two lanes to five to six to four plus four on a parallel carriageway going in the same direction apparently at random, and badly signed by British standards. And where we'd have a small roundabout or a simple four-way junction, even at the intersection of two main A-roads the Dutch seem to have a fascination with gigantic concoctions with multiple lanes. The
typical roundabout we went around, for instance where a B-road style through-road bypasses a town and a local road goes off, has two fairly wide lanes around a large central circle. The two lanes are separated by concrete kerbs, so that if you want to turn right you have to get into the (kerb-separated) right-turning lane a hundred yards before the roundabout. We did come across roundabouts with three concentric kerb-separated lanes, one to go right, one to go straight on or right and one to go straight on or left. I still can't work out how that makes sense. Each kerb-separated lane on the roundabout demands a kerb-separated lane in the rundup, and there's no attempt to gently guide you into the new lane, it just appears.
All this could, of course, be simply the prejudiced observations of a non-native being forced to do something he's not used to.
My best guess is that the default in Dutch road design is segregation, to minimise the risk that one road user has to interact with another. Interestingly it doesn't translate into road safety, whether measured by deaths per billion road km:
or by population:
The picture when you look at serious injuries rather than just deaths is horrible (the presentation of data is eccentric - it shows that for every death in the UK there are 2.7 serious injuries according to a standard international definition. For NL it's nearly 12 times. Unless I'm badly misreading the data, or it's terribly unreliable, more people are seriously injured on the roads in the Netherlands in absolute terms than in the UK.)
