Mine is the opposite. If the engine is running and I leave the vehicle with the fob in my pocket and shut the door I get the rapid beeps. I avoid the beeping by leaving the door just slightly ajar.
The best thing to do anytime you leave the car is to turn the engine off. The last claim I heard was that idling for 10 seconds uses more gas than restarting [doesn't take into account wear on starter., etc.]. But you've got to remember to turn it off. You're right, it's so quiet and smooth, sometimes it's really hard to tell.
I was doing some work with Habitat a few weeks ago. I pulled up my truck to unload a miter saw & stand and left it idle because I thought I was going to have to move it out of the way and park where everyone else was. There were a gas generator and a gas air compressor running all day, so you couldn't hardly hear each other talk, much less a vehicle running. I got to work and left my truck sit right where it was...still idling. Folks walked past it all day long getting stuff out of their vehicles and never noticed.
Six hours and a bunch of gas later, I got in and drove home. (bang) At least it was already warmed up.
