Teenagers are biologically driven to stay up late and wake up late, as shown in studies of sleep schedules in laboratory conditions: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2820578/

> Adolescents continue to show a delayed circadian (or internal clock) phase as indicated by daily endocrine rhythms even after several weeks of regulated schedules that allow for sufficient sleep. This delay is maintained under controlled laboratory conditions in which there is limited possibility for social influence.

Plenty of adolescents are not "biologically driven to stay up late and wake up late". I woke up at 05:00 or so nearly every morning when I was a teenager—per my internal clock—and I'm not alone.
