If you mean drive safely to ER I agree. If you are saying driving like a bat at of hell I disagree. The few seconds to couple of minutes saved in city services will make no difference. In frontier areas like mine the 5-10 minutes saved probably won't make a difference if they are that bad. But if while driving fast, blowing intersection the ambulance crashes you have lots more patients and the one you were giving a diesel bolus to still dies.
