I've long contended that DST is dangerous and a money hole, although not in the way that this article addresses. Anyone who lives to the west of a major metro area will understand my point.

Twice a year, once in the spring and once in the fall, commuters experience a period during which the sun is right in their eyes. For those of us driving east in the morning, and west in the evening, the sun is right in front of us all the time, and when it's at the right (wrong) elevation, vision is painfully obscured.

Earlier in the year the sun is too low to bother; later, the sun has risen high enough that your visor can block it. But for that time period, traffic is terrible because drivers can't see where they're going.

The thing about DST is that it resets this period. After having made it through once, DST drags the clock around so that we must endure the same sun glare again.

Once you start to think about this effect, it's clear that it must be costing fuel and lost productivity from the traffic, and likely even injuries and lives from accidents.
