This is only partially true, even in California. In Southern California, there is far less fuel than in prehistoric times, because there are more fires, and more high-severity fires from more ignition sources. In NorCal, the biggest blocker is often the local air quality district refusing permits for a controlled burn in the wildland, because it would cause unhealthful air. Which it would. So instead we wait for PG&E to accidentally a power line and make dangerous air quality. None of this invalidates your argument, but adds IC engines to the list of tech debt. Long unsolved policy problems are usually unsolved for a reason :frown:.
