When a vehicle runs out of fuel it returns to base, with the only options being Ok, Ok-5sec
Sometimes the vehicle arrives at night time to a mission that you want ideally to do during daytime.
In this cases, I don't start the mission and I put the vehicle to patrol over the target mission, waiting for daytime to come.
However, it could happen that before daytime arrives the vehicle runs out of fuel and just goes back to the base.
It would be very useful if the vehicle alerts of low fuel a bit before, so when this happens you can still move a few miles and start the mission.
