It sounds like you're ignoring quite a few things. First and foremost that car insurance covers a heck of a lot more than the cost of your car. It can also cover
- the cost of the other person's car
- your healthcare
- the other person's healthcare, including passengers in each car
- damage to other property like buildings and equipment that people drive into
- lost wages if you're too injured to work
- and a lot more.
The cost of a crash can be many times higher than the cost of your car. Of course maybe you only have liability insurance, which frankly is not a great idea and I would recommend getting comprehensive coverage if you can.
