but the bottom line question is: how hard is it to pass with a 2WD,
4WD, motorcycle etc.
That is a very complex question. You may add bicycle to the vehicles
too. Animals and humans .. too?
Soft surfaces may not support the vehicle weight (given a tyre size and
number).
Slippery surfaces may no provide enough traction.
Rough surfaces may though a vehicle off the require path.
Very rough surfaces may require lots of ground clearance. This might be
combined with the above 'rough surface'?
So that would be 3 measures .. they all have objective measures that
give numbers.. very few people would be able to measure and map them
though. And, as you say, they all change with weather and traffic. The
first vehicle to cross sand has a hard crust .. the next has a softer
surface.. after quite a few vehicles you get to a compacted surface...
with a covering of soft sand that has fallen back in to the grove.
Quantifying it is very difficult.
