I am so happy to find this!  My physical science students are going to really enjoy playing with this!  I can make a point about distractions while driving as well as teach a little kinematics at the same time.  This simulator is very easy to use.  Is there anyway to save the data and perhaps import it to a spreadsheet like Excel?  I have been manually recording and entering data in order to graph, etc.  Thanks again for a great resource.
