Everytime friends from outside Rotterdam cycle here, I warn them that it's not like te rest of the country. In Amsterdam it's not really frowned uppon if you go through a dormant red trafficlight, I wouldn't recommend that in Rotterdam. A lot of children in Rotterdam (in South) don't grow up with a bike, which is very much in contrast with the article imho.
I'm just pointing that out that it's not a total idyllic bike-paradise here imo.
