Well if you insist on comparing apples with lemons (British roads ain't the same as continental roads, both in concentration / types of traffic, provision of proper cycle facilities, driver attitudes, etc.etc.etc.) to try and 'win' an unwinable argument then you just carry on. I frequently cycle big miles on the continent, it's like a different world for a cyclist over there. However if you choose to ride without a lid, that's your choice and if / when you or yours have a big off, then that's your problem. The beauty of this is, if you have a big to do, and end up in a bad way / dead, where a lid would have helped, you won't be able to post about it, because corpses can't type.
Whereas pedestrian corpses can?
Pure emotive tripe
