Night racing is not much different than day.
When a real race driver learns the track, they establish a rhythm. Only paying attention to a certain few track markers for indication of braking, turn in, apex, and turn exit.
As a race driver is making about 1000 decisions per minute on track, they need to reduce distractions and ironically the track is one of them.
Turn out the lights and really only very few things change, the grip is reduced due to temperature, and a well rubbered in track can actually become very slick as that rubber cools, especially unpredictable off the driving line.
Try and identify those markers you can see both at night and during the day, establish your rhythm.
The same thing applies to being in someone's spray in the rain or having a foggy windshield...
It's quite common how many drivers end up with very limited visibility in races.
