Chatting with a fire dept trainer over at the pub, I asked about the state of the art for battling EV fires after hearing about situations where huge amounts of foam or water were used and the scene had to be cordoned off. Apparently the new thing is a "blanket" used to smother and contain the fire. Makes sense as that eliminates thousands of gallons of chemically contaminated water. He said he had no info on what the new blankets were going to cost and wasn't willing to speculate.
My last assigned vehicle was a Fusion hybrid, which I took from about 28K to just under 100k miles. Great vehicle, trouble free, relatively comfortable and the battery assist got it up into the 40mpg range on road trips. I'm totally against battery powered vehicles, based on cost, infrastructure and the ease of instituting draconian control and surveillance on personal transportation. I think mandating higher mpg standards would be a good thing and far more reasonable than trying to eliminate internal combustion engines. I've used CNG fueled vehicles and between CNG & hydrogen, think that is the way we should be heading.
I remember when BHO was running for President and his platform was converting all future private vehicles to CNG. Once he was in office nothing more was said about that....
