How is it possible to have a new MB350 [15 months old - fully serviced at MB dealership] catch on fire then burn to the hubs ?

What is your question?

To then realise... there is no vehicle fire extinguisher, intumescent protection and automatic fire extinguisher system in such as sophisticated vehicle - supposedly safe as transportation ? No dashboard audio & visual display warnings of danger of a car on fire with engine bay smouldering & smoking... such as 'pull over' & 'vacate' ! Photo series taken of the fire storm that engulfed the vehicle and resultant burnt out shell.
