The people you need to ask
The people you need to ask are not the car manufacturers, but the emergency personnel. If they have been told not to use the jaws of life on hybrids, then there is a risk. That is the only way to know; ask the people who use the jaws.
sat next to a fire captain
sat next to a fire captain on a recent flight and he told me about this. Mentioned a huge live voltage running through the hood??(which I am trying to google now) so no jaws of life. Also with fire in prius the batteries melt and hazardous materials has to be called to clean up the mess at a huge cost to taxpayers. I was surprised.
Before you make a judgement
Before you make a judgement you should read the article in firehouse.com. See what the firemen say.
