I come up from Naas to Dublin every day. Why is there a 100 km/h speed limit from Naas to Dublin where there is a three-lane road? I acknowledge it is a busy road. There is a motorway straight to Naas with a speed limit of 120 km/h but, all of a sudden, it drops to 100 km/h. It is 100 km/h to the M50 although it is a wider road with more lanes. With a view to having continuity for motorists, why is it not 120 km/h the whole way in? Most people do 120 km/h on it anyway.
