Not to mention the tremendous cost of energy as certain places in the highway slow to a crawl once again. Site some data, you say? Why? In a day when the political correctness picks and chooses and makes up it statistics (I won't mention names, Al, so don't worry). The people that decided that DST saves energy I am sure made up the stats just as badly as I am only they may have taken the time to find a few others that agreed with there sentiments.
But I am sure they did not do the obvious. You know, the unbiased thing: measure actual energy consumption in places where DST is done and where it is not.
