> When you go with dark mornings, you are combining the worst road conditions with the worst visibility.

You're still passing the buck to commutes during dark evenings. Driving at night is always more dangerous:

I'd argue that evening darkness is somewhat safer than morning darkness when I'm considering winter weather. The temperature of the roads are higher after ten hours of daylight than they are after ten hours of darkness. The coldest and iciest conditions are often found right before dawn.


Another important thing is, that people might be tired in the morning as they are not fully awake yet. This gets worse, the earlier they have to rise vs. the sun raise.


Also, on average, people are in less of a hurry after work.



My point is that given equal lighting morning is probably going to be worse for driving because of road conditions.

If we then have to add darkness to one of those, adding it to evening will probably be less damaging because evening has a larger safety margin due to better road conditions.

Adding darkness to morning is taking what is already the hardest case and making it even worse.


But currently more accidents happen at night than they do in the early morning, even when morning darkness factored in.

> You're still passing the buck

Well, yeah. That's the key to their whole argument: the buck HAS to be passed somewhere.
