This mod saves the point where you left your Savegame, so you will start at that point again, instead of always starting out at the same position on the map. (It doesn't matter if you are in a vehicle or not, you will start out next to the vehicle in case you left in a vehicle)
The mod is specifically made for people who play with the No-Teleport mod, but obviously can be used by anybody who doesn't want to spawn in at the same start point each time.
Warning! This Mod is Singleplayer-Only since I do not think that it is worth the effort to track all different players and their leaving/entering to the server for the "small" effect of starting out where you left.
