That is tiny. I just checked Uk legislation and it seems to require £1.2m cover for damage to property and unlimited cover for personal injury and deaths.
I’d prefer to be covered at double those amounts in case of some crazy and unlikely scenario like getting in an accident with a G Wagon where the other driver dies. There’s also $40M aggregate of personal injury protection.
For the parent, an extra 1M umbrella is an extra $2-300/y and covers beyond auto!
