I'd agree that things work better in NL for commuters.
Couple of counterpoints though:
Surfaces can be very poor and surface types change very frequently. Quite of a few of the dedicated cycle paths I use are in a bit of a state; last time I cycled between Hoek and Den Haag (last summer), the path behind the dunes was collapsing. Lots of roads, especially in towns, are made from herringbone bricks which often get a bit lumpy.
The Dutch seem quite fond of cycle lanes positioned alongside parked cars in the door space. Those always worry me.
Dutch drivers pass extremely close to cyclists, especially on one way streets where cyclists are permitted to cycle the "wrong way". Very few drivers will give you much space in those circumstances and they don't seem to make much allowance for children.
There are I think some striking differences between NL and UK cycle commuting:
Dutch commuters typically have shorter commutes and cycle more slowly than their UK counterparts; a commute over 10km would I think be rather unusual. The slower pace leads to less conflict with other cyclists and peds, at least in my experience. Following on from that, Dutch commuters rarely see their commute as a sporting event, wear ordinary/work clothes and use heavy sit-up-and beg-style bikes. All of this adds up to a greater air of normality and the entry barrier to cycling NL seems to be somewhat lower that the UK (no sporty-bike, specialised clothing, expensive anti-theft devices, helmet(!)).
Also, employers don't appear to be expected to provide special facilities for cyclists other than parking space - wheel benders being the most common provision. Some of the posters on this forum seem to suggest that they won't cycle to their workplace in the absence of provision of rather specific set of facilities (secure, indoors with showers).
