New generated road course (different random layout):
Trial-20: 2441 reward, 2206 steps, osc=0.029, RIGHT lane ✅
Trial-8: 2351 reward, 2922 steps, osc=0.295, RIGHT lane ✅
Trial-18: 2031 reward, 2214 steps, osc=0.032, LEFT lane ✅
Generated track course (completely different environment/visuals):
Trial-20: 2443 reward, 2207 steps, osc=0.030, RIGHT lane ✅
Trial-8: 2317 reward, 2868 steps, osc=0.284, RIGHT lane ✅
Trial-18: 2033 reward, 2216 steps, osc=0.032, LEFT lane ✅
KEY FINDING: All models show IDENTICAL behaviour patterns across ALL 3 tracks:
- Same oscillation scores (within 2%)
- Same lane preferences preserved across tracks
- Same step counts and rewards
This proves GENUINE GENERALISATION — not track memorisation!
