As a Paramedic, there is nothing more frustrating than trying to get to the scene of an emergency. There are so many vehicles on the road to begin with and not to mention the people who will not yield to an emergency vehicle. Your lights can be going and the sirens whaling, but many drivers will attempt to out run the ambulance.
While this may seem amusing to some, there is someone in need of emergency medical attention. It may sound like a cliche, but that person may one day be you or your family member. Remember to think of the sick and injured the next time an ambulance is trying to pass you. Be understanding, and allow the vehicle to pass unopposed.
