Not sure of the map number, but it's the map with the big excavation areas in the NE and SW of the map where the NE is fenced off with only one entry and the SW has the road and a house on the north of it.

Problem with this map is if you go to the East side, then attempt to use the road to go back West...the north/south road is so high that the Quad always gets stuck on the ridge of it when trying to use the east/west road to cross it. I can replicate the problem 100% of the time, and how slow or fast you are going has no impact on clearing the ridge of the paved road.

This is a massive pain in the neck because with how bush/tree heavy the map is - and the quad being hard stopped by anything bigger than a blade of grass - you literally have to choose which half of the map you are going to run across on foot every time you end up on it. I have screenshots of the ridiculousness if needed.
