Given that Daylight Saving Time (DST) costs lives, causes accidents, and saves little or no money, the practice of DST should be abolished at the Federal level.
DST was started with the good intent of saving energy consumption by reducing coal and other fuel consumption and reducing lighting requirements. These concerns have been overtaken by technology. The ubiquitous use of previously non-existent (or prohibitively expensive) air conditioning means that in southern tier States, DST actually increases electricity use rates.
Unforseen consequences of DST have been increases in heart attacks, industrial accidents, and motor vehicle collisions. The idea of some is that the switch back to Standart Time in Autumn ("Fall back") compensates, but in practice people stay up late instead of taking full advantage of the extra hour, and only an infinitessimal minority go to bed early before the DST "Spring forward" time.
The costs in dollars and time can be calculated, and are frequently debated. However, there can be no price put on human life and suffering. It is time to end the waste! The waste of lives, property, and resources must end.
