A recently unveiled plan for a car wash on Springs-Fireplace Road in East Hampton should not be considered in a vacuum. But that is, unfortunately, the sense we get from some members of the town planning board, who appeared favorably inclined toward the proposal presented to them on Feb. 3. They are, perhaps, to be forgiven because this part of town has become a place for businesses not welcome elsewhere. Whether that kind of use should be perpetuated there is an good question.
