Kinematic Trajectory & Sensor Sweep
T: 0.00sComparative Stopping Distance Identical 65 mph & road conditions
1. Perception & Actuation Latency
A vehicle traveling at 65 mph covers 95.3 feet every single second. Supervised vision neural nets process camera frames and command braking in ~150-250 milliseconds (under 25 feet). Average attentive human reaction time is 1.2 to 1.5 seconds (114-143 feet of unbraked travel).
2. Kinetic Energy & Deceleration
Stopping distance follows $d = v \cdot t_{reaction} + \frac{v^2}{2 \mu g}$. Because kinetic energy scales quadratically ($v^2$), even a small speed reduction during early reaction vastly diminishes delta-V and impact force if a collision cannot be completely avoided.
3. Surface Friction Limitations
No sensor or algorithm can defy friction coefficient ($\mu$). On wet asphalt ($\mu \approx 0.45$) or ice ($\mu \approx 0.20$), braking distances double or quadruple. Autonomous systems maximize survival margins specifically by eliminating human delay before threshold ABS engages.
