So I've been trying out roadbases all day and one thing that would really help is a ground crew radio command to help turn you around. There's not much room to maneuver on those cramped Caucuses roads and the nearby FARP personnel will happily refuel and rearm your jet, but help you turn around or get off the grass? "You're on your own, pal!"
Alternatively reducing grass friction while near a FARP would be also welcome. Not that I don't think getting stuck in the mud isn't realistic - it is, but in real life you'd also have support staff to help swing the jet around, and you shouldn't have to eject or spend a full tank max afterburning to inch across the grass.
edit: Placeable tarmac or hardened ground would help too.
