Unfortunately articles like yours are all too likely to give ignorant motorists the sort of justification for the type of bullying that most road cyclists experience from time to time (even if that was not your intention), and which only helps to further polarise cyclists' and motorists' attitudes to each other. And that's a shame, because most motorists and cyclists ARE considerate. If you didn't think that your article would have the effect it has had, I think your judgement was flawed, I'm afraid.
I hope you won't find your road cycling too traumatic - and even learn to enjoy it. Last year I rode somewhat over 9000 miles, mostly on Devon roads, and loved nearly every minute of it (the few unpleasant moments being when meeting inconsiderate or unobservant drivers). I use my bike as a fast form of transport into Exeter (I average about 20mph, and often go at about 30mph towards Topsham: faster than the car, or train, for the places I want to get to), and for exercise/leisure. The cycle paths certainly are a superb resource for those who are either too nervous, or vulnerable on the road - you've only got to see the numbers using the route all the way from Exmouth, and along the sensibly-done BITS of Topsham Road to see what a difference they make. But for others, the road is the least worst place to be - and, at the end of the day, I do have not only a right to be there, but that is exactly where Government advice says I should be.
I hope (and suspect) that you might be getting a rather better picture of a subject which is somewhat more nuanced and incendiary than you reckoned for. In the modern world where thoughts can be beamed round the globe in minutes, it's worth being careful what you write.
Happy cycling!
