Bit of an odd suggestion..
The ability for ambulances to queue at hospitals when full?
Will stop needing to travel crews in excess of 200km to hospitals at times.
Ambulances could enter a queue at a full hospital and when a patient space is clear they get to hand over?
Realistic addition and could be very handy, I'd certainly use it a lot.
Before any comments are made.. In these areas I have max hospitals and clinics.. I just get a high volume of high casualty jobs.
