Thanks Richard for your reply. It seems like something that could be applicable in many different places. I'm skeptical about trusting medical care to non-medical professionals but getting equipment that a lot of people know how to use such as defibrillators, epipens, or inhalers for anaphylactic shock or asthma attacks to those who need them quickly could be an interesting side use of Uber. Though I'm not sure how this would work in practice - imagine not knowing if you're going to arrive to an emergency scene or a regular taxi pick up!
