I’m not in a city with paid firefighters but they spend a fair amount of time responding to accidents.
What is interesting is that Firefighter Unions resist any change such as brown-out of engines (mentioned in article). They justify their existence by to demanding big engines to be called out common traffic accident and with paramedic calls. Local departments put thousands of miles on big engines, retire them and all the while they never fought a fire.
My town of 27,000 or so hasn’t had a structure fire in over 3 years. 98% of the calls are EMS. And the FD bills $500 for the ambulance run.
