Why not move the gas pedal too, when using cruise control then?

I'd support that. It does feel unusual in most cars' cruise control that you can push the accelerator to three-quarters of its travel before you start to accelerate (e.g. if cruise control is at 50–60mph).

If you push the gas pedal, you'd expect to go faster, wouldn't you?

They used to, but not by design. Back when throttles were still cabled I could feel the cruise control doing its thing by lightly resting on the pedal.
