Rest in Peace
There's another consideration that I haven't seen mentioned so far. If you drive yourself or a family member to the emergency room, you may have a much longer wait sitting the waiting room than if you arrive on a stretcher in an ambulance. Some people in Dallas learned that long ago, especially those with no insurance and are not going to pay anyway. A wait of many hours in the waiting room is common; some have even been known to die before being seen. So they've learned to call an ambulance.
