Your racondition is a callback that is called every time it receives a vehicle status message. This then calls publish.

I filed a ticket for future enhancement https://github.com/ros2/rviz/issues/1025

apparently some inconsistency with humble that is not caught on loading

Today I installed and started testing ROS 2 Iron, but RViz is consistently crashing on start up.

$ rviz2
[INFO] [1690575860.534941980] [rviz2]: Stereo is NOT SUPPORTED
[INFO] [1690575860.535036033] [rviz2]: OpenGl version: 4.6 (GLSL 4.6)
[INFO] [1690575860.704326140] [rviz2]: Stereo is NOT SUPPORTED
Segmentation fault (core dumped)

It was crashing with my launch files, so I tried standalone with same result.

If I source /opt/ros/humble instead, then it works normally so I don't it does not seem to be OS or driver related. (Note that humble also shows two more Stereo is NOT SUPPORTED messages, and then works normally.

Sourcing just /opt/ros/iron/setup.bash also crashes immediately on startup, so I don't think it is my setup.
