Absolutely pitiful driving from the woman in this Hyundai Elantra - first sighted holding up a line of cars doing approximately 50km/h in an 80km/h zone then sped up just before (and continued to speed throughout) the school zone. Traveling at approximately 75-80km/h through the school zone. Also failed to keep left on the Nambour Connection road heading eastbound (90km/h zone dual carriageway).
