Vehicle Sync V1.0

The harvester steers the grain cart. Unload on the go, in multiplayer. Leader/follower machine synchronisation, modelled on the real systems used on modern farms.
One player drives the combine harvester, another one sits in the tractor with the grain cart. When the tractor driver engages the sync, the harvester takes over the tractor’s steering and speed and keeps the cart right below the pipe outlet. The harvester driver can nudge the cart to fill it evenly. The tractor driver can take over at any moment.
The sync ends immediately when the tractor driver steers, uses the pedals, switches on cruise control, leaves the tractor or switches off the engine. It ends after 5 seconds when one of these lasts that long (the terminal and a blinking warning count down):
The tractor stays connected to the network, so one click engages the sync again.
Only vehicles of the same farm, or of farms with access to each other, can sync. Only the player sitting in a vehicle can operate it.
All other functions have no default key, so they don’t clash with other mods: open or close the network, join or leave, engage or disengage, set the home point, the four nudge directions, and release. You can bind them under Settings → Controls → Vehicle Sync.
The server admin changes these in the console. They are saved in vehicleSync.xml in the savegame.
