Okay, I got an email back.

Hi Sketch

You are right. We changed the naming of the roads in the cartouche (not sure if you remember how it was before, but there were a lot more road types) and now there is no 'dirt road' other than 4x4.

How about we name it (on the cartouche) "Dirt roads / 4x4 trails"? Will that be clear enough?

Basically, all a "4x4 trail" is is a dirt road. It doesn't mean anything other than that. There used to be a number of different types, but most of them were removed for simplicity's sake.

So, label the unpaved roads "4x4 Trails". The name may change, but the road will work the same way: it's just a normal dirt road that's gonna be avoided if the option is checked.

Hope that's clear enough!
