William Brady, a professor for Emergency Medicine at UVA urged people to use good judgment when deciding what mode of transportation to get to the hospital. "Things like chest pain, shortness of breath, a heart attack, a stroke or a severe asthma attack are just the beginning of the list of emergencies and without a doubt, those patients should call 911," said Brady. "One of the worst things that could happen, an Uber driver is driving you in and you could have a worsening of your condition that's going to distract the driver and could cause an accident."
