It seems like the ped-involved car jackings are A LOT worse in this game(IV) then in III, VC, SA, LCS, and VCS combined...? Even the LCPD will steal other cars-I have seen many times where a cop will jack a random vehicle in traffic OR worse yet-one from your Parking spaces...Normal Peds even jack your cars from your parking spaces far too often(mostly the ones in the North section of first island(Bohan?)-the second safe house you get in game AND the one in Hove Beach(Those are the worst for getting cars stolen). Another thing that is bad about the new car saving system is that the normal traffic and even cops WILL knock your cars out of their parking spaces(making them disappear 9 times out of 10). This is the reason why the Garage system was a lot better, as that never happened in GTA III to VCS(sure cars disappear at times, but not due to other traffic)..
