I don't believe EV cars are anymore likely to catch fire than gasoline cars. Either way, if a car catches fire in your garage you are in for a bad time.
It's definitely good to spread the awareness that many fire extinguishers are not suitable to put out lithium fires, though.
> fire extinguishers are not suitable to put out lithium fires
Only Class D fire extinguishers can put out lithium metal fires. But lithium-ion batteries do not contain lithium metal. Lithium metal batteries do so, but no EV uses lithium metal batteries because they're too dangerous. Class B fire extinguishers work just fine on lithium-ion battery fires. The difficulty with lithium-ion EV fires is that they tend to re-light, but water is still the tool of choice for putting them out.
