I am sorry for interrupting Ms Hegarty. It is just to feed into what she says. I see all the windows open. I just feel that that stems from perhaps not a particularly scientific approach. How can we assist public transport companies towards best practice in this regard? They cannot be faulted because we are learning all the time, but how could they be assisted with this? What technology could we put at their disposal? In other words, how could we make public transport reasonably reassuring for the public in greater numbers - or can we at all - in terms of air quality?
