It's practically impossible to cycle at night on roads without street lighting due to cars. Has been for many, many years. The people who would want to do it (generally people into the sport and out for training) just accept this. Nobody else cares.
Why ignore people who ride a bike for transportation?
When I was a teen, I rode 10 km each way to school next to a very busy road. In winter, it was still dark. The combination of rain and oncoming cars would make me completely blind.
Because you're a minority and most people haven't been on a bike since they were a child. For most people, their first experience on the road is in a car. They are completely out of touch with what it means to use the road outside of a car. The roads are owned by cars, even though everyone pays for them. This is the way it's been for years and it won't be changing unless we have a serious reform.
That really depends on where you live. Over here, most people ride bikes regularly. Car headlights that can blind cyclists should be considered a serious issue.

Even people who design bicycle facilities don't consider this. They'll happily install a bidirectional bike lane where contra flow cyclists are effectively riding against motor vehicle traffic. This puts cyclists on the wrong side of the headlamp beam.
