A motorcyclist was riding down a Florida highway, and rushed to the aid of a driver in the midst of a medical emergency.
The biker's helmet cam captured the wild motorist crashing into light poles and going up and down embankments outside of Jacksonville.
The out-of-control car kept going like this for several miles, eventually landing in a ditch.
Two nurses at the scene determined the driver was having a stroke.
The motorcyclist and the nurses cared for the driver until more help arrived.
