Tesla Autopilot Driver Monitoring Bypassed by Sunglasses While Asleep at Wheel
A Tesla Model Y was filmed on a British Columbia highway on July 5, 2026 with its driver asleep at the wheel wearing sunglasses while children were passengers. Tesla's driver monitoring system, which relies on eye-tracking, cannot function when sunglasses obstruct the driver's eyes, and the fallback pressure-detection method failed to identify the inattentive driver. The Royal Canadian Mounted Police launched an investigation.
What happened
On July 5, 2026, a 2026 Tesla Model Y was filmed on British Columbia's Trans-Canada Highway with the driver fully asleep at approximately 100 km/h, wearing large sunglasses and with hands nowhere near the wheel. Two children were asleep in the back seat.
Tesla's driver monitoring system relies primarily on a cabin-mounted camera that tracks eye position, blink rate, yawning, and head movement. Tesla's owner's manual states the vision-based system 'will not be activated' when the driver wears sunglasses or a hat that obscures the eyes.
When eye-tracking is unavailable, the system falls back to detecting physical pressure on the steering wheel, which cannot determine if the driver is actually awake. The sleeping driver in this incident was not maintaining hand contact with the wheel.
Reported impact
The vehicle continued to navigate the winding mountain road autonomously while the driver slept and children were passengers, creating a risk of collision or loss of vehicle control.
Index analysis
The incident reveals a gap in Tesla's driver monitoring architecture. The system's reliance on eye-tracking, which fails when sunglasses obscure the eyes, and its crude fallback method of steering-wheel pressure detection, allowed a completely inattentive driver to remain undetected.
Governance controls
British Columbia permits only up to Level 2 driver assistance such as adaptive cruise and lane-keeping. Full Self-Driving is not legal to use on British Columbia roads.
