And yet you're on here opining that BMW owes these people money, despite admitting you have no idea why the cars caught fire. That's not very scientific of you.
I worked in TV news for a long time. Crap stories like this one are what pushed me to leave.
For your edification:
Because if there's fuel on top of the engine leaking down and feeding a fire, it's a really good idea to wash that fuel away. They're also trying to cool the entire engine compartment concurrent with putting out the fire, because once the temperature gets high enough shocks start to cook off and become missiles that can kill. Aiming the extinguisher at the base of the fire makes sense because you have just a few seconds of use before it's empty. Fire hoses can spew water indefinitely at over 100psi and upwards of 300 gallons per minute. They afford firefighters the luxury of different techniques.
At any rate, I'm curious as to why you started a thread by asking us what we thought, and then proceeded to fling insults at those of us who bothered to respond to you. Accusing me of being a BMW shill, suggesting @Mustangman is a bad engineer, telling @VOLVO_V70 that his attitude is flawed and distorted...
I'm not going to flag your OP as trolling despite the fact that it clearly was but I am going to be very, very blunt, with the caveat that I will completely understand if @cdaquila decides what I have to say isn't for public consumption.
Your posting patterns around here have been exceedingly abrasive and strange. You are on the path to being ignored by everyone with the way you have been behaving. I strongly encourage you to think about what you're typing before you hit the send button, and consider how you would react if someone were to say the same things to you. This community is very slow to ostracize a member, but when it does it's permanent.
