The game has a few choice cars that players love: the Satellite Car that reveals nearby buildings on your map; the van that has the most storage space around; and everyone's favorite sports car for speed. Now, have a car with its own unique utility: the ability to tow another car behind it. Ideal for players who want to stockpile cars around their base, but don't want to bully their friends to do it for them in multiplayer. Saves gas, too.
It's useful, it's immersive, it works in single and multiplayer, and it's convenient.
