  • Not rated a person

    CATARC measured the system in its own test runs, and no crash outcome for drivers or passengers is reported.

Depth runs from 1, a convenience or time saved, to 5, a life or a livelihood preserved.

An independent assessment report supports the benefit.

The system’s part
Not isolated. CATARC tested the car with the system switched on, so the scores describe the system's own responses. There was no run without the system for comparison. The page lists a 254 TOPS intelligent-driving chip, cameras, radars and a lidar. It does not describe AI or show that the system learns from data.
