I just entered my info and compared to my current fantastically expensive insurance with Mercury.
I am in my 40s, over 25 years driving experience, clean record (zero collision claims or accidents, no comprehensive claims (windshields) in the past 5 years), married, drive 8000 miles a year. Drive a P3D+.
With Mercury that was $900 every six months. (This is with a $1k comprehensive deductible and $2k collision deductible!)
With Tesla Insurance it's...$900 every six months.
I set all the limits the same ($250k/$500k).
