Legal requirement for personal automobile liability insurance in Germany is 7.5M EUR for personal injuries and 1.2M for property damage. I was startled when I moved over here from Maryland, where $500k liability limit was the highest available from Geico at the time.
We have an umbrella liability policy for 100M EUR - generally recommended in Germany. Our home insurance is less than 300 EUR/yr. Most expensive insurance we have is long-term disability. However, we do not insure older used cars for anything other than liability, and certainly never insure consumer electronics. If a month’s pay could replace it, or it’s not something that absolutely must be replaced right away, we wing it. Insurance is for risks that we could not cover from savings or that would cause long-term financial hardship, not disappointments.
