...then why not ride over to the left a bit more ...
A question often asked, usually by non cycling motorists and a very valid question it is too.
We as cyclists should all ride to the left and in the gutter, it's our place, in fact it's the only place we're guaranteed not to be run over by a motorist. A motorist who after all has the sole rights to that stretch of tarmac, you know, that stretch of tarmac that we cyclists don't even pay road tax for. Motorists wouldn't be brave enough to ride the gutter for fear of their expensive alloy wheels coming into contact with a high kerb, or their low profile tyres being shredded by the detritus left in the gutter and what with the possibility of damaging the suspension when running over one of the sunken drain covers in the gutter, it just isn't going to happen. No... motorists won't ride the gutter for fear of damage to their precious vehicles, but they are more than happy to put our/your life at risk if you dare to be in front of them.
We cyclists don't even pay road tax, we don't require a license, we don't have registration, our place in the gutter, so come and ride the gutter where we belong...
As to my stance on road position... it is centre of the lane I'm in unless the road ahead is smoother than a baby's bottom with no sunken drain covers and I'll then move over a tad further left, but still give myself a good metre from the kerb
