Unfortunately I can't give an apples-to-apples comparison as I moved to Colorado, and Colorado has the 6th highest auto insurance rates in the nation:

My vehicle insurance went up from ~$600/6-months to $950/6-months. But according to that article, I'm well below average for Colorado. According to their research, a 40-year-old driving a 2022 Toyota Camry with an accident caused is paying $4000/year. I'm a 50-year-old with a 2019 Lincoln Nautilus with an accident and I'm at $2,000/year so I think the accident forgiveness from Progressive is true.
The reason vehicle insurance in Colorado is expensive is due to three factors. First, it's a top 5 state for auto thefts because post-2020 Denver decriminalized auto thefts for some reason (what did they think would happen when they did that?). This year they busted two big auto theft rings and thefts are down 30% from last year, so that should help. Also, Colorado is a top-5 state for hail; I park in a garage but they for some reason don't take that into consideration. And third, there is some type of liability limit on vehicle insurance that they don't allow in Colorado, so people can sue and get much more than that from insurers.
