An insurer undertakes considerable financial risk in insuring a driver. In the event of a claim they could be liable for a few thousand for damage or a few million if their insured kills or very seriously injures someone -pain suffering, loss of amenity, loss of dependency, loss of earnings, continuing medical care. These are all potentially very expensive heads of compensation.
The whole point of insurance is the contributions of many pay for the liability of the few. That's the way of the world.
If ever you were injured or lost your life due to another driver's negligence you would hope that your insurers would recover as much as possible to put you, as best as possible, in a position as you were prior to the accident or alternatively recover for your spouse or family who would not have you around to provide for them. Sobering stuff.
