A 10-month-old baby was in a car as it allegedly clocked 168km/h on the Pacific Highway on Tuesday, sparking a high-speed police chase in which a pregnant teenage driver is accused of crashing into another vehicle and swerving to avoid road spikes before being arrested after abandoning the vehicle. Kirsty Lee Parker, 19, was refused bail on Wednesday after allegedly driving the Volkswagen sedan that police attempted to stop on the M1 near Gosford on Tuesday afternoon, prompting a pursuit that was eventually abandoned amid safety concerns after a passenger climbed out of the window to film the chase. Passengers are heard excitedly yelling and swearing at police in footage livestreamed on social media, with one video showing the baby in a car seat while loud music plays through the speakers. One passenger is sitting on the floor of the back seat. The learner driver allegedly refused to stop and crashed into a vehicle near the Pacific Highway and dodging road spikes set by police in the Lake Macquarie towns of Swansea and Pelican as it continued its journey north.
