She took her case to court...and lost. Mainly, because her baby-to-be did not take up an extra seat in the car.
Then should she have been fined for having another passenger on her lap?
I knew a pregnant woman in Michigan who was speeding on a two lane highway, trying to get to a store or gas station where she could have a rest stop.
She got a ticket.
She went to court, and pled her case before the judge, saying that she was pregnant and that it is harmful to a baby if the mother holds her bladder for too long.
The judge was annoyed, but let the woman off. It pays to be pregnant in his jurisdiction. (Or have a husband who is a partner at a big Detroit lawfirm.)
