STP ped reaction to gun shots

I remember there being a True/False in the INI of STP about how peds react to gun shots in vehicle or on foot.  I haven't seen it in the past couple updates on STP.  I find that when shots are fired people seem to abandon their vehicle.  You can drive away after the call is done but I like to clean up what I can.  Meaning, all those abandon vehicles I usually just call for their ins co and they come pick it up.  I was thinking I would change the option back to just having to drivers drive through, possibly running you over as they freak out.  I'm not sure which is better.  But, I don't see that option anymore on what you want the peds to do during a shoot out.  I think it would be good if they can just back up/turn around and drive away.  I'm not sure if that is possible programming/coding that (whatever you call it).  So, I think that was an option in the STP ini but I don't see that option anymore.  Unless it is somewhere else.
