The new mental with the vehicle spawning inside is MUCH better than having to leave the compound and getting fucked by cops. The area is also better as it's closer to both Rebel and HQ. While yes the sand sucks, there's a dirt road to the right that you could take and the trees offer concealment for the cops to actually push in. This makes it a much more balanced fight for both cops and rebels with a quicker response rate for the cops for more action.
