EVs can cause pretty bad fires from benign looking accidents. Perhaps this is for the best? Better safe than sorry as they say.
Or perhaps we should dial back on how many firefighters we keep employed at all times.
So over the last several decades, "firefighter" has really just become emergency responder, where "emergency" can be a lot of things that happen in society pretty often.
When there is a fire you still need enough at location in time.
The fact that there are enough in short distance with good equipment is one of the things which causes the low number of big fires: once the mandatory detector goes of for a little fire they are on site before it becomes big.
The problem is you need a good number when there is a serious fire, even if it doesn't happen very often.
