I would slow down to a speed limit of 5, even if I was sure it was a defective display. It's effectively an unknown speed limit. Maybe not if I'm very familiar with the road, but not everyone is. Yes, I'm sure the courts should throw out the ticket, but sometimes they mess up, and often you lose time and money to pursue your case.
