15 minutes ago I was riding home on my new great bike. Ahead, a plume of smoke and confused cars. I speed forward and see van smoking. The smoke is thicker and billowed more than steam would. With many onlookers, and nobody helping a
lightbulb went off --- bystander effect:
you should do something.

The van reversed back into the parking lot, and waited for a few seconds, I approached. A woman on a powered wheelchair emerged from sliding doors. A guy in a red truck had it parked 50 feet away, and was on the cellphone. I confirmed that he was calling 911.
The story becomes humorous.. I ask her to please back away from the van. She does a bit, but is concerned over her CELLPHONE which she left in the van.
So I try to coax her farther away. She gets the brilliant idea ---
I should should get her cellphone. I say "no", and she's flustered. Then she remembers a fire extinguisher in the back of the van, and she wants me use it. That's more reasonable, but I still don't want to because:

A. If we simply back up, there is a 100% percent chance that we will be safe.
B. I am no car fire expert.

I don't want to get her more angry, because I want her to listen to me. As she tries to persuade me to get her extinguisher, pass the buck. "911 will tell us what to do, if that's the right thing". She instinctively knows what 911 would say, they would tell us to go away and wait for firemen.
To her credit, the car was not in flames at this point. There was just alot of smoke coming out of the hood. There is a chance that I could have put out the fire. (If the extenguisher had the right chemicals, and was large enough, if I could pop the hood, and the nature of the fire).
The smoke is increasing, and some guy runs into the scene with his own fire extinguisher. She tells him to grab her cellphone, he does, and he tries to pop the hood to put the fire out. He does not succeed in extinquishing it.
The fire grows with visible flames on the hood. The extinguisher man has the sense to get out, he can't win. The guy in the red truck helpfully points out the the tires can explode.
I really had a tough time keeping the woman as far back from the van as I would have liked. She'd ignore me and take her joystick and maneuver around me. She was a decent looking woman in her 30's. To her, I was a young, annoying, dork-like obstacle -- in her way.

I am self-conscious around disabled people, I do not touch them, or baby them, unless they ask for help or whatever. But I almost needed to grab her chair. The entire situation must have looked like a scene from Arrested Development.

The firemen arrived, the car near totaled. We watch as the fucker burn, with a small crowd. The woman made some phone calls, upset about the van, and repeating how " he could have saved it, I had a fire extinguisher in the back". (Can you rub it in my face a bit more?!). The firemen put out the fire, but the car was destroyed. I picked up my bike and rode off. Finally, it should be noted that
my bike is great and everyone is safe and sound.
