Fuel system for vehicles

[Bakura]

I marked the fuel stations on a map. As a comparison, I also marked the Pay 'n' Sprays, where the cruise has to stop anyway. There are quite a few fuel stations not too far from a pay 'n' spray, and even near mount chiliad, there are two fuel stations. So if the fuel-system is configured properly (drive around the map with a full tank for example), running out of fuel shouldn't be a problem.

Also, like theHolyCow mentions, refueling outside a fuel station for a higher price is also a possibility, and there won't be a problem with a refuel-truck or something like that.
Another possibility would be a option to teleport to the nearest fuel-station, which would work as some sort of 'virtual' towtruck, just like the current taxi doesn't require somebody driving a taxi. This should be a expensive option, because players should refuel before they run out of fuel.

The map:

The red markers are the fuel stations, the green ones are the Pay 'n' Sprays. I think I forgot a few sprays, but maybe I'll fix that later.
