Yes it’s absolutely necessary! There needs to be firefighters to control traffic, if needed extract people from the vehicles, provide first aid until the ambulance arrives. And if you are seeing a bunch of private vehicles it means they are volunteering! And the so called parties are usually training or fundraising events. Why don’t you volunteer instead of complaining! If you ever need them to get you or your family who are stuck in a wrecked car before it catches fire or before the die because they are mangled in thousands of lbs of metal or fiberglass you won’t be whining about the help. Or if your house or a local business catches fire next to your property you will be the first to phone and expect a fast response. And you should be grateful for that.
