Maybe it's just too early in the AM, but your poll question seems backward. Does a "yes" mean they made a mistake, or they should have done it? Having lived through the NEMA wars, I believe banning them was the correct move. The separate division might have been a good idea if there were enough of them, but wouldn't they be supermodifieds? Of course, the supers also banned them.

And, don't forget that, until the IRL/Cart guys managed to get the correct (and very expensive) chasses in use, those cars were very dangerous.
