There's many more pros to living on the California coast than just weather, like proximity to nature, cultural and culinary diversity (a pro if you're not a white nationalist who hates seeing/dealing with people of color), endless food and entertainment options, a strong job market in many fields, and most of the problems you listed are highly dependent on the neighborhood/city. But it's ok, I don't really bother to argue with people who have an anti-California bias. To each their own, everyone has different preferences on where they like to live.

Also your use of the word "highway" as opposed to "freeway" which is the dominant term in all of California kind of outs you as a non-Californian. So I'm not sure if you visited and hated it or are just bringing up talking points you've heard.
