Which Traffic Signal Would You Prefer?

The flashing green light is common in Austria, but very difficult to find anywhere else.
In following countries (sometimes only partially in use): Mexico, Slovenia, Slowakia, Cambodia, Cuba, Canada, Baltic states, Israel, Russia, Turkey.....

In Spain they have combined green/yellow (at same time)

In Austria (all) traffic lights run this way:

red - red/yellow - green - flashing green (4 times) - yellow - red

But I think it is ok and helps estimating Your 'point of no return'; I miss it always, when I'm abroad....
