Absolutely beg to differ. I was on a high-deductible, low-benefit plan for a two-year old used economy car in Louisiana with no marks on my driving record for $250/month. The insurance cost was more than the monthly cost of the car. That being said, it was more than the state mandated liability insurance, but it still wasn't anywhere near the levels of insurance I now have in Washington State on a brand new Tesla Model 3. As you mentioned, it's highly dependent on where you live, but it's absolutely feasible to be paying $200-$300/month for insurance.
