Well being a sad ba****d i know that a touring car bodyshell does nothing above 12mph but cause drag because it starts to deform. so i think they will get to a point and hit a brick wall. so i think if we all turned up and geared the cars to the moon etc and went for it the 12th scale and tourers would leave us standing off the line but once our bigger wheels and tyres came into play we might have a chance especially with the advantage of balloonage
