I remember a tv show on traffic trials in court. Something like your day in court.
Most of the violations we on over speeding.
One of the violators reasoned out in his case that he overtook the car in front of him (driven be an old lady), causing him to over speed to avoid getting into an accident. He described the erratic driving of the old lady, slowing down and speeding up, and moving out of the lane for no apparent reason.
