I like this idea, I would give it a try,
+1. It will be more realistic, and the president will be able to withstand a few Hydra strikes, or to break through the terrorists awaiting around President spawn to devour the president like vultures.
I'd suggest giving 3000 health points to FBI ranchers, limos, washingtons and sentinels on President spawns. Of course, without any magic of this kind:
If president get in a car ,automatically that car is gonna got 3k health (if this possible)
We used to have ambulances giving health in old PTP once upon a time? Well I think there should be placed an ambulance in President Spawn zones, so only security or president can use it maybe.. But we have health & armor spawns more than one place in maps. So I don't think kind of thing needs to be added anyway..
Afaik, it was SAMP v.0.2 feature: you received armour if you got in Enforcer, and you received health if you got in ambulance. Actually it was quite nice and useful, I'd like to get it back,
+1. But I think it is a matter of another topic.
