Composite chassis must pass FIA crash tests (front impact, side intrusion, rear impact, rollover); Power unit elements limited per season (penalties for exceeding allocation — covered in Sporting Regulations)
Why people argue about this
People often assume that composite chassis in F1 cars are just made of carbon fiber, which they believe is inherently strong and doesn't need crash tests. But actually, these materials can be tricky to predict their strength under impact, leading to debates about how thorough the crash testing must be for safety compliance.
