Just to pick up on something the Senator has said for the record of the House, he made the point that the UK is looking at miles per hour, whereas we of course are looking at kilometres per hour. It is a really important distinction as there was a campaign in place more broadly about the concept of "20 is plenty". That figure of 20 referred to miles per hour whereas we are implementing kilometres per hour. Perhaps the more appropriate speed limit on many estates would be 30 km/h. We are simply making the option available so that if, in any particular circumstances, they want to go lower the option will be there. As has already been said, the difference between being hit at 30 km/h and 35 km/h is life changing in terms of the potential harm.
