The new cars seem to be so big that 3+ wide action wouldn't be possible in the almighty iTCC
No deko shouting "3 wide, 4 wide, 5 WIDE BACK IN THE FIELD!!1!"for the Rockingham round, would be sad to watch!
But oh well, perhaps it's not a matter of cars but a matter of track. Who knows, perhaps they decided that releasing the track in 1:1 scale would be too much work to do, so they decided to stick with the 1:4 scale... Perfect to produce a Bristol style feeling. And the Banger dudes would be happy hey!
