Vehicle recovery

[Imp]

I was just thinkin like the old SPwaw, if it was a simple terrain imob there was a chance that it might get out after time, sometimes 5 or more turns

See now we are in territoty I know about as used to offroad & without getting help if you dont get unstuck pretty quick you just plain dont. The only exeption is a light vehicle & a couple of shovels on soft ground or snow drifts but now you aare back to the over an hour category. Besides dont take the game so literaly the scale means everything represents many things from combat to terrain immob. No traction, wiped out the transmission, water in the engine, rolled it etc.
You would need sticking effect by vehicle class Jeep truck APC etc & there is a case for motorcycles (& cavalry) becoming unstuck. You either totaled it or didnt but should also check you for injuries & ability to carry on. I would say most people want changes in the way things work without thinking it through just based on gut feeling so think about a bit. Tanks probably most annoying to get stuck its on a river bank tracks spinning digging its own hole or 1 metre down in the mud what is the real chance it will get out unaided. Call in the weasel & a bit of luck & we will say 1 in 10 manage to free themselves. In game terms what is the point you will rarelly see it happen, say you are reckless & stick 3 vehicles a game you might get one mobbile out of the 3 games so effect on play is squat. If you manage to stick more than that well avoid slopes Mud Swamp if have to only move on with first MP. Most like stream rough you are fine if moving slowly 8mph or so which is 4 hexes above that you are taking a gamble & driving through fast. Note this means in fact your chance of getting stuck is very low you can drive over as many rough hexes as you like so long as they are within 4 hexes of your start point & do not have a slope.
As said before this means you probably lost some MP the turn before getting in position to cross, count them as time lost because of the terrain. This also produces bottlenecks correctly upon encountering difficult terrain as everyone bunches up so good gold spot territory.
