I'm constantly surprised that insurance in certain other countries has a liability limit - you pay $X to have $Y coverage, where $Y coverage is a payout limit.
In the UK you pay $X for Y coverage, where Y is not a pay out limit but a type of insurance - so fully comprehensive (you cause the damage, your car is fully covered as well as all liability for any damage to third parties), third party (only liability for any damage to third parties is covered) and a range in between (eg third party, fire and theft which covers you for loss or damage to your vehicle from those things).
When there is a pay out, there is no limit to that pay out - you have to cover for someones car being written off to the tune of $50,000? Its covered. You have to cover for someones life long care after you cause them to become disabled to the tune of $100Million? Its covered.
I pay the equivalent of about $500 a year for fully comprehensive insurance for a Landrover Freelander.
