Currently with Blockade, you can currently block two directions, but somehow you can block both 'west and east' and 'north and south' at the same time. Considering what this means, it essentially indicates that you're somehow blocking both sides of the road despite there only being one vehicle doing so. On a two-way street, this somehow means you are essentially in two places at once. I'm sure you can see how this doesn't make sense. Seems like an oversight of the system?
