I agree with jp1.
At the same time I opt for the highest deductables available, I need savings in a bank or credit union "for the unexpected". My practice is to put in 100-200 dollars per month. I have never had a claim, but if I did have a claim, the deductible could wipe out my reserve for the unexpected. Additionally I would likely need to sell stocks and bonds.
I did shop around when I first became a customer for auto insurance. I shopped around again when I became a home-owner, and I concluded the most competitive quote would be on bundled insurance with home and auto coverage from the same company. Since then, years of claims-free insurance resulted in a discounted premium on the bundle. I have not shopped around in the past ten years, but I suppose I should, just in case there is an insurance company that is more competitive than the one I am with now.
I understand that I could get auto insurance with (potentially) a lower premium if I have a chip installed in the insured vehicle which would monitor my safe/unsafe driving habits, miles traveled, etc. I personally would not sign up for this. I generally don't appreciate surveillance on me. I wonder if the parking lot, in-store, in-park-pavilion, and doorbell cameras are nearing a saturation point. Besides, I brake for birds, deer, and even turtles on the lonely forest roads around here... I understand that "panic braking" would be reported to the insurance company by the chip as an unsafe driving incident, and tend to increase my car insurance premium.
