I've been "saved by the bell" a few times now at traffic lights when I was dozing/inattentive/being a moron while sitting there and not noticing the light turns. The dings come quick enough that they supersede the honk from behind.
But at intersections with combined arrow lights with one green and another red at the same time, it doesn't work at all really.
And the LED speed signs inside tunnels it likes to see as traffic lights also, causing momentary braking action every 200m or however often these repeat. Super annoying. And a little bit embarrassing. Car drives like Helmut the taxi driver from the movie "Night on earth". Ok. I just really dated myself. Haha.
