Yeah, it’s true that most children are driven to school these days so that particular reason for reverting back to GMT/UTC would not be as valid now as it was in the 70s. There is an argument being voiced at the moment to retain BST for economic and certain environmental reasons, ie. it would result in reduced energy consumption for light and heat, it would be beneficial to both domestic and business users in terms of cost. It’s a difficult one, the needs of people in Shetland at 60°N and those in Cornwall at 50°N are quite different. I’d prefer to keep GMT because, even with GMT, where I live the sun rises after 8am between the end of November and the end of January. I’m not a morning person so I need all the help I can get in terms of daylight to wake up.
