A significant and growing portion of the driving public reports being “temporarily blinded” by modern vehicle headlights. Some drivers now link that glare to specific, severe accidents.1
Simultaneously, the “intelligent” automated systems designed to control these lights are facing scrutiny. These same systems, which also steer the vehicles, are being recalled for sensor failures 2 and are implicated in a growing number of fatal crashes.4
This report investigates the intersection of these two public safety crises. The first is the “glare epidemic” from OEM headlights. The second is the opaque and fallible nature of Level 2 Advanced Driver Assistance Systems (ADAS).
It seeks to answer a key question: Are these systems a safety feature, as marketed, or do they represent a new, unregulated hazard?
Executive Summary
This report investigates two critical and intersecting public safety concerns: the widespread public outcry over dangerously bright OEM headlights and the opaque, fallible nature of automated “intelligent” systems, specifically Automatic High Beams (AHB) and “lane tracking” (Level 2 ADAS).
Key Findings:
- The Glare Paradox. A major disconnect exists in public-facing data. The public reports a “glare epidemic” from OEM headlights, with anecdotes linking glare to accidents.1 Conversely, official IIHS data shows glare as a factor in less than 0.2% of crashes.6 This report demonstrates the systematic flaws within the IIHS data. The IIHS self-admittedly cannot track the primary crash type: a glare-blinded driver running off the road.6
- ‘Intelligent’ Failure. Automatic High Beam (AHB) systems are not advanced AI. Manufacturer manuals explicitly state these simple camera systems are known to fail. These failures occur in common, high-risk scenarios, including fog, rain, snow, hilly roads, and sharp curves.7
- The ‘Black Box’ on Wheels. The AI models and source code for mass-market ADAS suites (e.g., Toyota Safety Sense, Honda Sensing) are proprietary. They are not public for review.10 The industry’s internal validation standard, ISO 21448 (SOTIF), relies on secret virtual simulations.13 This means the public has no way to verify what scenarios are (or are not) being tested.
- Documented Dangers. These systems are not just theoretically flawed. They are the subject of official recalls for sensor failures.2 They are also cited in civil lawsuits alleging fatal defects 10 and widespread owner complaints describing “ping-pong” behavior 8 and “fighting the steering assist”.8
- Manufacturer Accountability. Skepticism about manufacturer accountability is misplaced. The National Highway Traffic Safety Administration (NHTSA) has broad legal authority to compel data from all automakers, including foreign ones. This is evidenced by NHTSA’s “Standing General Order” forcing ADAS crash reports.4 It is also proven by its history of levying millions of dollars in fines for defect-reporting failures.16
This investigation concludes that the primary risk is the “Expectation Gap.” These systems are marketed as “intelligent” but are, by design, brittle sensors. This gap between marketing and reality creates an unreasonable risk. It encourages drivers to trust a system in conditions it is not designed to handle.
