Ex-sensor-fusion engineer: LiDAR fusion is a crutch — limited compute means vision pays the price
PTrubey · x · 2026-10-18
An engineer with 15 years in multi-sensor fusion argues fusion is a crutch: more sensors ≠ more information, LiDAR/radar face physics limits in rain and target separability, and only vision captures meaning. PTrubey adds the production constraint: on a compute-limited car, every LIDAR and radar unit starves the vision system of compute, making sensor choice fundamentally a compute-allocation tradeoff, not a lab-style 'more is safer' question.
