- "although a diesel may have started the fire, the involvement of EVs could well have made things pretty bad ?

To be clear, it was an electrical fault in a diesel car that was the cause of the inferno.

The following may be relevant:

"When investigating the fire’s environmental impact, the team at BFRS tested surrounding water samples and found little trace of lithium and cobalt – two vital ingredients in electric car batteries...

"What fire teams did notice at the scene, however, were signs of so-called ‘running fuel’ fires, which may have played a key role in the inferno spreading as fast as it did. The suspected cause of these are the plastic fuel tanks fitted to most modern production cars; plastic tanks, such as the one fitted to the Range Rover that was the source of the blaze, are described by the BFRS investigators as 'more susceptible to failure in the initial stages of a developing fire', thus causing the flammable liquids (i.e petrol and diesel) inside to flow out and set alight." (Auto Express, Oct 2024)

Of course, although a diesel may have started the fire, the involvement of EVs could well have made things pretty bad ?

More likely things were made pretty bad because I suspect most people would have ensured their fuel tanks were fairly full for the return journey home. I doubt if we are alone in filling up at our local supermarket shortly before a return trip to Luton.
