Mr. Cormac O'Rourke:

I was not aware of that. Perversely, despite the fact that people drive faster on motorways, they are by far the safest roads in the country. Visibility is good on motorways. Speed limits are a policy matter. However, I do not think the speed limit affects motorway road safety to a great degree because, unfortunately, accidents happen in the main on secondary roads. I am not convinced that speed limits are the biggest issue with regard to safe driving. I am not an expert on speed limits.
