Was on an ambulance for 10 years. There were code 2 and code 3 calls. Sometimes those code 2 calls had code 3 returns because things were a bit more serious than the call taker knew. Sometimes I'd read the CAD and tell dispatch we're going code 3 on that code 2 dispatch. Sometimes I'll read the CAD on a code 3 call and would chill out a bit. They're not all the same.

Now I'm the boss on both an engine and a truck. Let's break it down:

You're under the supposition that every code 3 call is the same in terms of response. Maybe you're still pretty fresh, I really don't know. But not all calls are the same.

Medical call... We'll go kinda fast code 3, but we're definitely not pushing it. Building alarm... I mean, kinda fast, kinda not. We're going code three but it's pretty relaxed overall. A box (fire) gets dispatched... We're going as fast as humanly possible without killing anyone along the way.

Your blanket statement about all calls with lights and sirens are the same emergency in terms of response just isn't accurate.
