ScenePilot: Controllable Boundary-Driven Critical Scenario Generation for Autonomous Driving

arXiv:2605.21168v1 Announce Type: new Abstract: Safety-critical scenarios are central to evaluating autonomous driving systems, yet their rarity in naturalistic logs makes simulation-based stress testing indispensable. Most scenario generation methods treat surrounding agents as adversaries, but they either (i) induce failures without explicitly modeling vehicle-road physical limits, yielding visually extreme yet physically unsolvable crashes, or (ii) enforce physical feasibility or policy feasibility in isolation, which can over-focus on aggressive maneuvers or remain tied to a controller-dep

Why this matters
Why now

The increasing complexity of autonomous driving systems requires more sophisticated and realistic simulation environments to ensure safety before deployment.

Why it’s important

This development addresses a critical bottleneck in autonomous driving by creating more effective methods for generating safety-critical scenarios that are both challenging and physically realistic.

What changes

Scenario generation for autonomous driving testing can now more accurately model physical constraints and agent behaviors, leading to more robust and safer systems.
