To be honest, does it really make that much of a difference? I mean, wow, the morning will be darker for an hour longer, but its the winter anyway, the amount of time it "light" is shorter anyway.
In relation to the Times article, I really dont want it to be light until 11pm during the Summer thanks. Mainly as it will only encourage the less socially aware members of the public to stay out on the streets longer and cause more annoyance to the rest of us.
I cant see the view expressed on safety will stand up either. So, by the thinking of the writers of the study, its safer to drive in a low-in-the-sky sunset than it is when it dark? ********, if you out on any main road at twilight, you will see people with sunglasses on, people with no-awareness of if they should have their lights on, people with the sun-visors down... all of which, IMHO, contribute a alrger hazzard to road safety that driving in the dark, when its bleeding obvious that you need you lights on (yes, Im aware that you still some some tools that dont have them on, but hey you cant help some people)
