So, as they say in ole blighty... on yer bike dear.
Assumptions, assumptions ... and lack of clear comprehension,
deary.
I mentioned 'the flatter cities of Northern Europe'.
Perhaps I should have been more specific, in order to assist those lacking knowledge of geography and culture, and taken care to identify the cities of Northern Europe most commonly associated with mass cycling - most of the cities and the road network of the Netherlands, the road network and several cities in Denmark, parts of Belgium, parts of north-west Germany, Helsinki, Malmö ... nowhere in the UK even rates a mention.
However, I am sure that many hundred thousands of Dutch, German and Scandinavian bankers, builders, teachers, technicians and others, of all sexes, ages and status, would be amused if they were to read that they are all lumped together as dippy-hippy mothers!
The UK's transport planning seeks to make the use of the public highway by non-motorised users to be as uncomfortable, unpleasant and even dangerous as possible and as I already stated in the post to which you have so inaccurately replied, the UK is following the US closely in their efforts to prove that car is king.
By the way, as far as I am aware, I was not carried on a bike in any fashion while I was young. We lived in a very hilly area. Any brain damage from which I suffer comes from falling off horses and ponies in the days before modern protective helmets were even invented, not from being dropped off a bike from a great height. And it's a physical impossibility for my knickers to get in a twist ...
So you're even inaccurate in your sarky comments, too!
