I don't think I'd dare ride a bike round our country lanes! we have narrow winding roads, sharp corners, 10@ and more high hedges, and in some places the trees meet overhead and turn them into tunnels! Some of our local roads are narrow enough to have a grass strip up the middle... and a tarmac strip for the wheels! the grass tickles the cars tummy as you drive along! The roads are also used by folk who think that they HAVE to drive along at 60 mph, or 80! And combine harvesters in July and August, and tractors pulling trailor loads of apples at this point in the cycle.
And muck spreaders...
