I often see ladies with two children riding on a single bicycle in London. One is seated in front of her and the other baby is behind her. When I first saw this, I was shocked and thought that she must be really confident with her cycling abilities. I thought the UK was the Kingdom of Health and Safety. In the summer of 2013, I saw a lot of mothers riding bicycles in Copenhagen, with a much safer-looking carriage attached for their children to ride in. The carriages have enough room for more than two children. My fellow artists and I agreed that they were better. But is it safer?
