I take it none of you are wheelchair users or suffer from any other chronic conditions that render you unable to live a 'normal' life?

Before further pontificating from the able bodied just reflect on some of the suggested solutions, imagine yourself post motorbike accident, and then see how you would react to the restrictions put forward.
