Many countries' traffic lights go from Red to Yellow and then Green instead of directly from Red to Green like in North America. It makes more sense to me since it stops people from looking at the cross traffic lights instead.
I hated them when I visited the UK back in the day, not so much in high traffic situations, but because in light traffic, when the lights went yellow both ways simultaneously, two drivers, both "sneaking through on the yellow" could have a very unpleasant result.
Maybe UK drivers of the time were less wild than Oz drivers, as I didn't see that happen, but it always worried me!
Other delights were "three lane roads" with the middle lane available for overtaking from both directions, the roundabout outside Southampton with a small hill in the middle, & the propensity of drivers to drive on their parking lights at night.
The latter, which had just become illegal in 1971 was still widespread, & combined with those godawful Sodium lamps made cars without any yellow in their colour scheme virtually disappear.
Another side effect of not using dipped lights was that many lights would be grossly out of adjustment, causing glare to oncomers, & of little use to the user.
