There are already a lot of threads on Tesla insurance, so you may want to check them for specific suggestions. Note also that insurance details differ by region, by driver, by coverage details, etc., so what's good for one person may not be good for you; and you certainly can't compare exact insurance costs with other drivers on a national (much less international) forum.
My own recommendation is to go to an agent or site that will enable you to compare rates from several insurers; and/or check multiple insurers yourself by calling them or asking for an online quote. I did this before buying my Model 3, and found huge disparities in rates -- about a 6x range in costs, IIRC, although one of those was an outlier, so excluding it resulted in a range of more like 2x or 3x. FWIW, my previous insurer was Geico, but it was one of the pricier options (but not the outlier), so I dumped them and changed to Progressive. Most other people who've mentioned Progressive on this forum say they've given good rates. Geico has mixed reviews; some, like you and I, have reported high rates from them, but others say they've got good rates from Geico.
Also, Tesla plans to roll out their own insurance plan soon. I gather they're working with an established insurance company, but I don't recall which one. Their idea is to use driving data from your car to incentivize low-risk driving habits, but I don't know the details. I also don't know how close they are to rolling out this product, but you might want to look into it if this idea sounds appealing to you.
