Investigative Context & Clinical Notes
Based on ESPN's investigative analysis into motorsport culture: Inside a race car reaching 200 mph, microsecond decision latency increases by over 140ms under Grade 2 concussion profiles. Drivers face intense structural incentives—long-standing consecutive-start streaks, high-stakes playoff cutlines, and eight-figure sponsor agreements—that historically normalized masking symptoms.
