Prius (2010-12) :: Flames Shooting Out From Underneath Right Headlight

Drove my car on Wednesday morning for about 5 minutes, when I parked and turned it off, sensed a really bad and strange smell but couldn't pinpoint if it was the car, or the parking garage at home (which is underground, locked), or outside. Dismissed it from my mind. Two hours later, drove the car to work (10 minutes) parked it in underground garage. Turned engine off. Coming from hood on the right side. Got out, thinking I would lift the hood and have a look but as I approached right side of car I could see flames shooting out from underneath the right headlight (could see the flames through the headlight). Took a bit of time to find water hose in the parking garage but finally got it out.

Car is a write off.... absolutely was not sabotaged, no arsonists, nothing ..... Toyota guy from Toyota place across the street walked over to have a look, said it was a total loss. Doesn't seem like Toyota is really concerned either! I was really shaken as I feared that there could be a chain reaction of all the parked cars going up in flames. Smoke was thick, people were choking... seems that other than getting a cheque from the insurance, there is nothing I can do to find out the cause of the fire. People keep saying in various forums that nothing is located on the right..that could catch on fire.
