# Traffic contact visibility check (r323)

The packaged L4RA viewer was loaded in Chrome 150 at Route 450, distance 700,
with the Celica selected and ambient traffic enabled. A held-W drive moved
through the crossing at up to 13.1 m/s. The traffic contact guard fired at the
next proposed player position `(-940.12, -330.46)`; the road-support guard did
not report a failure. The capture at
`webgl-city/review/images/466-r323-traffic-contact-visible.png` shows the car
continuing at 14 mph after the input was released, with traffic visible ahead.

This confirms the viewer's visibility and contact boundaries are now aligned
in a live browser run. It does not establish the retail collision shape or
traffic reaction. The preview still applies a center-distance cutoff and does
not simulate the stock traffic driver's collision response.
