It was a frightening scene in Boynton Beach, Florida when a car drifted across a busy intersection into oncoming traffic. It was a medical emergency; the woman in the driver’s seat was slumped over the steering wheel. A woman who knew the driver sprinted to help her, but she couldn’t stop the runaway car alone. She waved to other drivers, who hopped out of their vehicles to lend a hand. Together they were able to stop the car and help the driver.
