One important point you fail to mention is attorneys. An insured can bump someone in the rear and barely crack the tail light and you will get a letter demanding $50,000. I have experienced this many times over the last few years. Here is an example of the worst claim. My insured was carrying $300,000 combined single limit. His teenage son was backing out of a parking space. The other vehicle driver, who was driving a jacked up 4 wheel drive pickup, wanted the parking space so he pulled up too close and my insured bumped the truck. My insureds son called the police. The police arrived and said there was no damage to either vehicle so there wasn't a need for a report but since they were there they would write up a report. A year and a half later my insured was served with suit papers. The statue of limitations in Georgia is two years and the attorneys like to wait just before the statue of limitations expire. The suit wasn't asking for a dollar amount but whatever a jury would give. Six months later I received a copy of the claim check which was for $90,000. I called the attorney for the insurance company and asked him why he recommended settling for $90,000 when there wasn't any damage to either vehicle and no one was hurt. The attorney said that three days after the accident the claimant had neck surgery and he couldn't risk going to court and the claimant getting more. He also said he thoroughly checked the claimant and if he could have found where the claimant had ever been treated for a neck problem he would have not settled and that there were thousands of people driving that have a health problem but don't have insurance or the money to pay for treatment and wait for an accident to happen so they can get their treatment paid. I could go on and on with cases like this that happen all the time. This is a problem for insurance companies. I read recently where many insurance companies had to go back to last year and add millions of dollars to their reserves for claims that had cost more than anticipated.
