I think signs going up the inside of big vans/ lorries as warnings to cyclists are a good thing. When i speak to new cyclists, i tell them never to go up the inside of lorries/buses etc first and I tell them a simple rule...."if it is big then keep away from it" as in keep clear of coaches/trucks/buses/flatbeds etc just cos they are so dangerous and they often have limited visibility.
the last few comments by somebody I find just a bit bizarre. - Uranium? Builders becoming teachers/Doctors? wtf?
i think we need to restructure society.
