Are you sure about cars being 6 studs wide and bigger vehicles being 8 studs wide? The 6 stud wide vehicles already have a hard enough time passing eachother on roads, 8 studs wide would make driving a nightmare! It would also throw the scale off. Now that I just checked, normal city vehicles are already 6 studs wide if you count the bulky tires. It seems weird to me that they would change the scale(vehicles having trouble passing, being to big to get in garage doors etc). I think I'm looking the most forward to the car transporter
