Meh... sounds like yesteryear. In my experience in modern cars, 12v is more likely cause. There are a few issues in that marketing material that aren't quite jiving with my experiences putting out those fires.
Same with my experience doing failure analysis.
Bulk of any rv/boat/buss/truck/semi fires are traced directly to bad or failed 12v wiring.
It is a standard because of age NOT SAFETY
24V is a far better value in modern, current(Amp) hungry vehicles, and better in a shock hazard sense as well
Low voltage = High current
High current = more heat potential (I^2*R)
This is why we run houses at 120/240V and not 6 to 36V
