“Take The Wheel” what happens after ?

There were a episode here, where a older man has a seizure and had the car on autopilot. The car slowed down and put on the hazard light and came to a full stop. 
I wanted to figure out what the Karoo does. 
so I tried driving and not putting my hands on the wheel while on autopilot. 
after a while the bling bling “take the wheel” appears. After that, the sound is louder and more annoying. Then the car makes small breaks. 
I did not try any further then that. Does anyone know what happens next?
