I am gonna choose to not respond. 
Just as an aside, I contracted for some fire safety training at work once where we trained people in using a fire extinguisher. Everyone put a fire out and it was drilled into us to shoot the extinguisher at the base of the fire not on top. So then why are they sticking the hose under the hood instead of underneath? They hose the cars and house down from the top down, instead of from the bottom up. Just seemed like it had little effect on the flames. Remember that though folks, shoot that extinguisher at the base. It runs out very quickly so you only have one chance.
You are very right.
I took fire safety programs for 21 years and was taught the same.
And that technique always worked.
Do you know what a flash point is? The flash point is the temperature that organic compounds give off sufficient vapor to ignite in airā¦Yes earlier what I quoted was the temperature at which gasoline vapors ignite so my apologies for typing quickly without completely reading through post first (work has been busy tonight), but you seem to be more interested in nit-picking everybody elseās answer over technicalities even though several of us have said that youāre wrong.
Gasoline has a US DOT flammability rating of 3 for a reason, because the vapor
Hereās an MSDS sheet for unleaded gasoline:
And yet youāre on here opining that BMW owes these people money, despite admitting you have no idea why the cars caught fire. Thatās 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 thereās fuel on top of the engine leaking down and feeding a fire, itās a really good idea to wash that fuel away. Theyāre 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 itās 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, Iām 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 distortedā¦
Iām 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 isnāt 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 youāre 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 itās permanent.

If that statement were true, then the diesel engine would not exist as a diesel engine do not use sparks or flames to ignite.
Edit.

I screwed up. This response was/should be directed at MR. andrew_kennedy7, not You. Sorry.
The problem with fires being caused by Ford cruise control switches involves high electrical resistance (meaning heatā¦) being applied to brake fluid which has leaked into the switch.
If brake fluid will ignite with heat then gasoline certainly will. Iāve never had a reason to throw gas on a hot manifold to find out.
Somewhat ironically, gasoline dripping on a hot manifold is less likely to ignite than oil.
The gas vaporizes so quickly, it never reaches its ignition temperature.
A glowplug (alternatively spelled as glow plug or glow-plug) is a heating device used to aid starting diesel engines.
@shadowfax has a good handle on this
@andrew_kennedy7 asked " So then why are they sticking the hose under the hood instead of underneath?
When firefighters approach the car they will hit the fire direct and when possible bounce the water on the ground to try to drive it up underneath, especially with an engine fire. Up close there is not enough room to maneuver the hose to get a decent angle, unless the ff lays on the ground and angles the nozzle up. Dangerous for the ff and if we can get in on top we can flood the fire with water/foam. A truck will have anywhere from 500 to 1,000 gallons of water. Rare that we cannot put a car fire out with that. If we run out, the next due in truck has more water. Hand held fire extinguishers give you no more than about 10 seconds, aim for the base, if you canāt put it out back away and call for help. These are only good for small fires that just started, once the fire gets established do not put yourself in jeopardy with a hand held extinguisher.

No worries I figured as such
I have a friend whose boat, unattended caught fire in the garage, quite a mess, so he bought a new boat, parked it next to the garage and it caught fire luckily only damage to the siding, go figure. First one was caused by the battery as best I recall, second no conclusion as I recall.
I am looking for a sailboat.
My dad taught me sailing and I love it.
There should be little risk of a fire.
But you never know. 
Have an old Alcort sunfish, neighbors on the lake were very interested in buying it, some people like old boats and cars I guess. Maybe even me, bought a 53 Johnson to put on our 50 Crestliner, paint is faded but Alsakan kicker beer a good rendition, Retirement planning for the old boat parade.
Maybe they left their vapor cig charging and used an incorrect charger.
How long was the sunfish ?
On another note.
I was advised that I may be banned from this site.
I have made some posts that were less than positive.
For that I sincerely apologize.
I try hard to do my best and try to always be encouraging.
I ask for forgiveness.
I think the alcort sunfish is 14ā now just to perturb people fishing for real sunfish, the sunfish gather by the dock as we walk down the stairs, some times if we are really generous we feed them canned corn. Now we might get 40 or so and can hold the bread an inch off the water and they will jump and get it. So when off the lake critters are fishing for our sunfish, we go feed them, kind of like pets they are, Whoa look at that one, grandaddy sunfish. Sure I probably piss them off, but I care not, I love feeding the fish and having them around.
Car related Highway is being redone and lake association agreed to a public boat launch. DNR is like this is not a destination lake and there are so many public access signs along the road you should not expect a significant increase in cars launching boats. No invasive species yet, one of the 10% clearest lakes in MN, too much money to create private boat launch for cars and trucks, our old launch now inaccessable due to 2 to 4 lane expansion of the highway. Pretty primitave as we say, it is hard to tell probably a 6ā drop between the asphalt and the water.
I wish to learn how to fish.
My previous experience with fish was advantageous to the fish.
I used to fish about every day. My dad and I would fish on the weekends on the lake or on the ice in the winter, and during the week Iād take my my bike to the dam and fish. Been many many years now since Iāve wet a line.
I hate doing it but video car is carp, so car related, we could have a lot of fun exchanging music videos,
To Andrew Kennedy, I have driven hundreds of class 8 diesel tractors. Only a handful of them were equipped with glow plugs.
