If people are that close to the edge then leaving for work an hour earlier / losing an hour's sleep is only a proximate cause to their death.
The root cause is that they were leading a fucked-up life and were susceptible to a final straw. Now, whether any given individual's life is fucked up due to their own choices or not probably runs the gamut from 0 to 1 on probability distribution.
Excuse me. I know you inner city trash don't have to deal with this.
However, us drivin' folk in flyover states need to deal with the sun as it affects VISIBILITY.
See, that thing you see between the buildings and through the smog and smoke called "the sun", when it gets low (behind buildings) it reflects off the road pavement, or sometimes ice and snow, and gets in one's eyes. I know you can't see it then, but it really does this.
Going to work (in a car, not a train or a subway or a bus) during one week of the year is more hazardous due to bad visibility during peak traffic times due to the sun being low on the horizon (that's "skyline", to you city slickers) because the low sun and reflective pavement obscure vision and shorten the distance available to react. It also makes it harder to discern the markings on the roads. This peak traffic accident week happens once a year regardless. Daylight savings time makes it happen TWICE a year.
