As I understand from the news reports lately, ambulances are overtaxed in this city. So people who really need an ambulance (bleeding profusely, heart-attack, cannot breathe etc.) are not getting responded to quickly enough. Labor, in most cases, is not an emergency. Labor is an expected event and unless you are losing blood or having other alarming pains (besides contractions) I think it is not right to call an ambulance. On the news a few weeks ago they were talking about how recently several incidents have happened where the ambulance has even broken down in transit to the hospital--because the fleet is old and has not been replaced by newer vehicles. The same news report was talking about how people are calling for the ambulance for things like constipation. So, as long as taxis are willing and able to get you to the hospital safely, it would benefit the whole community if you didn't further tax the already over-strapped ambulance system unless you truly have a life-threatening emergency going on.
