What happened
David Kidd and colleagues at the Insurance Institute for Highway Safety (IIHS) tested automatic emergency braking (AEB) that responds to bicyclists. They used a 2023 Toyota RAV4 and a 2023 Subaru Forester on a track. The cars approached a bicycle target crossing at 15 km/h at 40, 50 and 60 km/h in daylight. They also approached a slower bicycle target ahead at 50, 60 and 70 km/h by day and at night. The authors report that the AEB systems completely or nearly avoided the bicycle in the daytime crossing tests. They did so with the bicycle ahead by day and at night with high beams. At night with low beams, the systems only marginally reduced speed for the bicycle ahead. The abstract gives the results for both cars together. Traffic Injury Prevention published the study in May 2025. IIHS wrote in 2023 that Subaru had introduced a third generation of EyeSight on the 2022 Forester, designed to prevent both crossing and parallel bicycle crashes. No crash avoided on public roads is reported.

In controlled evaluations, the AEB systems completely or nearly avoided the bicycle target in the crossing path scenarios during daytime and in parallel path scenarios during daytime and at night with high beams.

Insurance Institute for Highway Safety. Subaru's bicyclist detection shows positive results. News release, 6 June 2023. Cited for the generation of EyeSight on the Forester.
The third generation of EyeSight, which is designed to prevent both crossing and parallel crashes, is already available, though it's too soon for a study of its real-world effectiveness. Subaru introduced the new version on the 2022 Forester and WRX in the U.S. market.

AI system
- Workflow
-
The car approached a bicycle target crossing at 15 km/h at 40, 50 and 60 km/h in daylight. It approached a slower bicycle target ahead at 50, 60 and 70 km/h by day and at night.
Follow-up
- Conditions for replication
-
At night, the high beams are on, since the systems only marginally reduced speed for a bicycle ahead with low beams. The bicycle crosses the car's path or rides ahead of it, as in the tests.

Road vehicle crash avoidance.
- Purpose
-
Subaru built EyeSight to warn the driver and brake automatically when a collision is likely. IIHS writes that its third generation is designed to prevent crashes with both crossing and parallel bicycles.
