When I pedalled to the left side of this truck, I noticed smoke that I thought was coming from the truck itself. I figured that I should turn around to figure out what was happening so that I could report it to the police. It seemed to me that smoke was pouring out of the exhaust pipe. When I called Berkeley emergency, the first question I was asked was whether the burning car was on Oxford. When I said yes, the dispatcher informed me of the steam vent beside the car.
I was a bit embarrassed with my mistake. I would have been even more embarrassed if I had not reported a burning car that exploded!
