I don't think you need to broaden your mind and I do not think that anyone is suggesting that. I think you need to be less timorous. I certainly believe that legislation can change things. We cannot just accept this situation. A lot of places in Europe have banned lorries and HGV's from driving at peak times and in rush hour. That might be a start. And how about this http://www.eilidhcairns.com/wd81/ which sets out to improve safety measures on these vehicles. There are things that we can do.
HW, that was a very measured response to my rantogram to an earlier one by Raa (which did suggest I took a very narrow view).
I absolutely accept that there are things that can be done - and I think that London (and other metropolitan areas) are headiding in roughly the right direction. Slowly, but things are changing. I cycled to school in SE1 in the mid-70s as a 12-year-old. things are way more focussed on bikes now than they were then.
What I do not think, however, is that there is an appetite for change among the woider population.
I notice in this thread something that looks like anger at politicians over the tragic deaths of cyclists. I'm not sure that ire is well placed.
As to my need to be less timorous; I think if you saw me riding in London you'd withdraw the sentiment. I'm afraid my urban riding style and road positioning are based on my time many years ago as a motorcycle courier.
Anyway, your response was nice to read and not at all finger-pointing like the earier one from Raa - for which (genuinely) thank you.
