Here is where driving a car at dark vs. into the sun differs from driving a bus at dark vs. into the sun.No bus, just a car. Twice a day everyday, into the sun both ways (when it's out).
I much prefer to commute in the dark rather than at dawn or dusk.
When you're driving your car at dark, your headlight shine onto the road, this lights your way. Yes, it's exceptionally challenging driving into the sun. Which is likely why you feel it is easier to drive at dark. I would agree for the average driver, driving at dark is better.
Now, try spotting tiny little kids off the side of the road in the dark vs. spotting them while driving into the sun? I'm sure they both have their challenges, but I don't have any first-hand experience with it so we'll just say that they are a wash either way. But now consider that when driving in the dark it doesn't matter which direction you're driving, it's challenging in the dark period. But when the sun is coming up, you're only challenged when facing that certain direction. So consider that the sun gives you problems when you're facing into it plus or minus 20 degrees we'll say. That still leaves 320 degrees of other directions that aren't impeded/challenging. That means that driving early morning, with the sun coming up is only 11% as challenging as driving in the dark.
Of course there are a few assumptions made here, but I think my example will convey the point that driving with the sun coming up isn't nearly as challenging as driving in total darkness where your headlights do not illuminate your intended target.
