For me the low sun is the most dangerous driving obstacle, more so than ice or anything else. I'd like to see the stats but I've noticed a lot of accidents on mornings with clear skies.
Oh well, soon we'll be driving in the dark.
I had a case about this not long ago. My client had to stop for a traffic jam and was rear-ended by a driver who was blinded by the sun. His argument was that he didn't have to pay for damages as this was force majeure.
In Belgium however there is a general rule that you should always adapt your speed to the weather conditions (I'm pretty sure this rule exists almost everywhere). So I argued that even if he hadn't been speeding, he was clearly driving too fast. If you're blinded by the sun, it is irresponsible to continue at the same speed even if you're not technically speeding. So even if he was blinded, he was still in the wrong.
We ended up winning the case, but I must admit I have mixed feelings about this. I know you should slow down, but that's not always easy to do. Especially not when everyone around you is driving fast.
