Memory definitely plays tricks as I really only remember one particularly dark winter.

Also it does seem that there was an overall reduction in the number of accidents as a result of the change, even allowing for the introduction of drink driving laws about the same time, but the increase in accidents to youngsters in the morning had a greater impact on public perception than the reduction in the evenings. It shows how important perception is, often more important than actuality.

Overall reading the paper, I suspect the change will come. Opinion poll results suggest that even in Scotland there is a small majority in favour of the change.

Personally, I will not be happy about such a change, but like most things, I will undoubtedly come to live with it.

I do find the argument about work times etc. put forward by business a little weak. After all large countries such as the USA, Canada & Russia manage to cope with multiple time zones, so why not us with just one one hour difference from the rest of Europe.
