# L4RA intersection drive and neighborhood stream check (r279)

Packaged Chrome opened the corrected Route 450 start at L4RA radius 120. An
8-second throttle/steering sequence moved the 240SX about 78 world units from
the seed pose into the casino intersection. The neighborhood stream updated to
center `(-900.2, -383.8)` with 26,712 triangles and 140 textures. No road
support or building collision failure was reported. The car encountered an
ambient vehicle and the viewer's contact check reduced its speed to zero; a
short steering/throttle input moved it again to 7 mph with no active collision.

At the final frame, four ambient cars were reported on road-supported route
poses, with world-up Z above 0.9993. The capture shows one car entering the
intersection; no building visibly crosses the pavement at this viewpoint. The
ambient motion is still the static free-roam route follower and the player
contact response remains an approximation. The road is dark and the 240SX body
is still a pale paint fallback.
