I am not getting 600km/tank :(

Oh sorry about that, I missed the "stuck" bit, I was thinking you meant rolling down a hill or something. Yeah, of course. If you are in a jam and stationary, go to netural and put on the handbrake. To save fuel here, don't creep every 1/2 metre that moves, wait for at least a 2-3 car's lengths, then start moving slowly, because if you have to brake and stop, you have just wasted more fuel.

In stop-and-go traffic, if everyone was waiting 3 seconds to go, after the traffic came to a stop, the effect would be accumulative and nobody would make it home for dinner. Best thing to do is make-up the 2-3 car length after you get moving and then start to drive like the truckers, they're constantly on the move, even in stop/go traffic.

If you have a manual transmission and in slow moving traffic (that hasn't come to a completely stop), there's more opportunity to capitalize on the DCFO, instead of idling in neutral while completely stopped.

That's good advice, and what hypermilers attempt to achieve in traffic like this. Our term for it is "Driving Without Brakes", or DWB, meaning we try to maintain constant forward movement by picking the right speed to let us not use our brakes at all, or come to a stop. The whole idea is to conserve momentum.

If you're trying to save gas, wouldn't it make more sense to get the car moving, as soon as possible, once the traffic starts to move? And once you're on the move, slow it down a bit to make up the 2/3 second gap (which is easy to do since most drivers tend to be too hard on the gas pedal during stop/go driving).

Why sit and let the car idle unnecessarily (in neutral) for 2/3 seconds when it could be moving? Not only are you wasting gas, but you're delaying traffic for everyone else that's behind.
