I worked for one of the BIG ones, our algorithms showed that 9 years was the point where the chances of a claim was highest. Not necessarily from the fault of the insured party, could be someone crashed into them, but once a claim is made the algorithm shows that another incident will soon follow.
Another fun fact, we could see everything you typed into the information fields on our website before getting a quote. So, if any of you are thinking of being less than truthful, or bending the said truth, to "front" a policy for example, just be aware
THEY CAN SEE EVERYTHING YOU TYPE INTO THE BOXES.
Swapping names, job titles, parked on or off road, annual mileage, we could see everything people had done. It was a very quick way of getting a denied claim.
"No MR Reynold's, we don't think your fiesta was parked on your non existent driveway when it was stolen, you just didn't like the quote when you said it was parked on the road overnight, so you lied to us" !
"How do we know you don't have a driveway?"
"BECAUSE WE HAVE GOOGLE FLIPPIN EARTH AND HALF A BRAIN!"
