Benchmark checker Robotics and driving

Is nuScenes open-loop planning still meaningful?

Status:Flawed Checked against the report, 5 November 2026

Verdict

No. Baselines without any perception compete, so its scores say little about driving.

Why flawed: Simple baselines that use only the car's own state compete without any perception.[1][1] Ego status in open-loop driving, arXiv 2312.03031 Primary The chapter rates it Discredited.

What “Flawed” means

Known problems

  • Ego-status baselines without perception compete with full systems.[1][1] Ego status in open-loop driving, arXiv 2312.03031 Primary
  • The best open-loop method correlates with closed-loop simulation at R² = 0.7, against 0.8 for NAVSIM v2.[2][2] NAVSIM v2 pseudo-simulation, arXiv 2506.04218 Primary

What to look at instead

NAVSIM v2 now fills the gap with pseudo-simulation on real data.[2][2] NAVSIM v2 pseudo-simulation, arXiv 2506.04218 Primary

  • NAVSIM v2 Status:Still useful Yes. It is the main public driving benchmark, and its hard split stays at 34–37.
