No one ever seems to get criminally or civilly prosecuted for starting the fires. Often everyone knows who did it but there's no irrefutable evidence and the police aren't interested - perhaps as a policy because it's understood that some controlled burns are useful. California's police could equally well be told to "focus on other priorities" instead of investigating fire starters.
Grass fires are not considered a significant danger in CA... it's the big canyon fires with 20+deg slopes rising 1000m covered with Eucalyptus and other large trees interspersed with scrub brush that create firestorms and can easily burn 40km^2 per day even with mild winds.
I don't know if this is realistic. But we have a pretty litigious society these days in Ireland too - behind the US, but ahead of almost everywhere else - and I can't find any evidence of a successful civil suit for starting a wildfire. I did find this which says there are practically no criminal cases:

If it's ok for people to just start fires without any particular authorization or restrictions, then it's not clear to me how you distinguish them legally if the consequences should be particularly bad.
I just don't understand logically, how you can define arson or negligence without clear rules.
It's clearly incorrect that California just doesn't care. After all after https://en.wikipedia.org/wiki/Camp_Fire_(2018) PG&E was charged with 84 counts of manslaughter.
Also, remember Sergio Martinez? https://en.wikipedia.org/wiki/Cedar_Fire

I'd guess that in decades none of them have or it would have been in the news and nobody would have done it again... Lot's of rural places burn garbage in the US. They just don't do it where there's a high risk of burning down the neighborhood.
You'd get into serious trouble doing the same further north in Germany, Denmark or Sweden.
the USA just has a culture that talks about suing people a lot more; in practice, Europe and the US do so at about the same rte.
They also tend to let law enforcement know, and law enforcement and fire people seem to understand the purpose. People from the city still call 911, but that's just because they are trained to think that distant fires are dangerous. To be expected.
