Expanding the map doesn't pause gameplay, but instead just shows players a further zoomed out view of where the player is, where the roads are and where objectives may be located. (gamingunion.net)
I didn't really think this through when I was taking captures and failed to get a longer zoomed out view on cylinder 1, the ignition timing mark, was short on time etc... (mechanics.stackexchange.com)
However, one issue that really affects those with vision problems is just how zoomed out the view can be in multi-player levels. (dagersystem.com)
