What matters is that you can make a safe journey from A to B without having to mix with dangerous traffic.
I don't see traffic as 'dangerous' any more than I see stairs or electricity as 'dangerous'. Sure, these things can kill, but I've negotiated all of them without accident for over 40 years. I'm not about to avoid roads simply because some timid cyclists see them as deadly - and I'm certainly not going to sit quietly while some government tries to force me off the road (which we in the UK and the US use by right).
In the Netherlands, you will find an alternative option to almost all heavily trafficked highways...
You assume I want an alternative option. I don't. I'm a grown-up - I can handle the road just fine. I commute on a six-lane highway every weekday - I'm perfectly comfortable handling complicated lane-changes on such roads on a regular basis..
From my brief observations, the road bikers, whilst rare, were happy to use the parallel lanes too.
I'm sure many are - I'd say most cyclists have been gulled into being happy to use such 'apartheid' facilities - the equivalent of a '
blacks only' drinking water fountain, such as could be found in South Africa until quite recently. Many sincerely believe that bike facilities are built for the convenience of cyclists. I don't feel that way. I've cycled a good thousand miles in the Netherlands, and I can assure you, I was not 'happy to use the parallel lanes' - the parallel lanes were slow, dangerously narrow and had a surface which was generally of poorer quality compared to the road. Dutch roads are perfectly good - so if I prefer the road, why should I be forced to use the bike lane?
Segregation, whether race-based or vehicle-based, is founded in bigotry. It cannot serve the needs of the group it subjugates. Sadly, there are plenty of 'Uncle Tom' cyclists who are glad to cowtow to 'Massa' and stay off the roads.
