Tesla's Cybertruck Outperforms Model Y in Contrived Fake Wall Test

Tests reveal significant hardware differences between Tesla's HW3 and HW4 systems, reigniting discussions on sensor technology and FSD reliability.

Mark Rober's initial test showed Tesla's Autopilot system failed to detect a fake wall painted to resemble a road, while a LIDAR-equipped car succeeded.
Kyle Paul's follow-up tests demonstrated that Tesla's Model Y with HW3 hardware and FSD version 12 also failed to detect the fake wall, requiring manual intervention.
In contrast, Tesla's Cybertruck with HW4 hardware and FSD version 13 successfully stopped before hitting the wall, highlighting advancements in detection capabilities.
The performance disparity raises questions about Tesla's reliance on a camera-only system versus multi-sensor approaches like LIDAR and radar, which are widely used in the industry.
Tesla has not confirmed whether the Cybertruck's additional forward camera or Phoenix radar is integrated into its FSD operations, leaving uncertainty about the specific hardware contributing to its improved performance.
