I agree. It's just a matter of getting used to checking for cars visually. You already have to do that with bikes when crossing bike lanes.

During a transition period I can see it being a problem since listening for cars it can be a strong habit. I had problems with cross walks in the US at first since many of them don't emit a sound when it's green. I would often stand around subconsciously waiting for the sound to indicate that I can cross, and I'd miss my turn.
