A street driven car without windshield wipers is just asking for trouble. If you're going to put street tags on your car, most (if not all) States will fail inspection without them. Same for no defrosters. You can get away with this (if you feel foolhardy) with Antique, Classic, or Vintage tags that don't require inspection.

That being said, the stock Lucas wiper setup leaves a lot to be desired. The street rodders must have a better way of doing this.
