It is also their moral and legal duty to take precautions. Stopping at traffic lights the other day I mentioned to a fellow cyclist, a stranger, how dangerous cycling was. I had just narrowly escaped being run over. I would be really depressed if I were to give up cycling, but giving up beef for a year or so until the evidence is clearer is no trouble at all. Happily he agreed, and we pedalled our separate ways, my helmet firmly on my head.
Life is a risky business.
