New vehicle (from Mercedes of encino) was being driven in a test drive. Eb on burbank bl-speed limit 50mph--in center lane of 3 eb- mbz salesman reached across driver and set cruise at 40mph and encouraged driver to test the collision prevention system---traffic ahead was stopped at light---salesman continued to tell driver to not apply brakes--driver did not apply brakes---collision avoidance system failed--seat belt tensioners failed---air bags did not deploy when S550 collided with rear of stopped vehicle (eclass mbz) at approx 40mph. Back seat passenger (driver's wife) was hospitalized for cracked sternum---driver was seen by chiropractor for aggravation of lower back muscles--------mbz encino still has the vehicle, presumably in post crash condition. Meeting is set at mbz encino for March 20, 2015 to inspect vehicle. My attorney will be in attendance.
