Rates between states aren't really comparable. But to answer your question directly, I was paying about $1000 per year prior to switching to pay per mile. This was for full coverage also, 1 vehicle purchased new in 2020. Going by averages from wallethub:

As someone who has worked on auto and homeowners insurance rating and programs for the last 15 years, making comparisons between what others pay is fraught with issues. The best way to do it as a consumer is to try a site like compare.com to see what yould pay in another location. With that said, I have recommended pay per mile programs to everyone I know who has flexibility in their driving patterns. Depending upon which program someone chooses, long trips can be an issue as some programs cap what they charge you in a day and others don't. The programs do make mode of transit decisions a bit clearer, autos are more likely to win versus air when multiple people have to travel. For comparison purposes, on a recent trip to Phoenix, the driving would have saved me $250-$300, but cost me 14-16 hours of longer transit time. I flew.
