Car 1 cut in front of car 2, car 3 (ours) stopped 1 car length away, when started to drive past the crash suddenly car 4 slammed into car 3 (ours) and pushed my wife's car into car 2 and car 2 into car 1 again. airbag failed to deploy, seat belt locked and ems had to get my wife out. when this happened my wife was driving on i95 heading south just passing exit 60 hypoluxo dr at about 45mph when she was able to stop. she was going less than 5 mph when she was hit by car 4....updated 11/05/15 *bf *js
