In December of 2016, our firm resolved the personal injury claim of a female truck driver who was rear ended by a Toyota Tundra pickup.  The pickup skid approximately 30 feet before slamming into the back of the 18 wheeler.  Based on the amount of milk and cereal on the windshield of the pickup’s windshield, it was apparent that the driver was distracted by the bowl of cereal he brought along to eat on the drive to work that morning.  As a result of the hard impact, our client suffered aggravation to her lower back which required invasive surgical procedures prescribed by her treating physicians.  The defense hired by Farmers Insurance was focused on the lack of any significant damages to the back of the 18 wheeler’s trailer although their client’s truck was completely destroyed.  Failing to understand the basic physics concepts, they hired a well-known engineer who has made a career working for insurance companies to opine that the “delta-v” of the pickup truck was too small to cause any injuries to the trucker.  However, in his deposition, he could not show the math in how he calculated delta-v or show the values he used in his calculations.  Because he could not show his math and because he based his opinions on just photographs, the judge prohibited him from testifying without showing the math.  Farmers Insurance tendered the policy limits before trial.
