They’ve been doing it in the States/Houston for ages.
It works quite well, you give way to the person that arrives at the junction first, then wait your turn until it’s your time to go across the junction, they’re called 4 way stops at crossroads.
They also have a right turn on red policy where if you can see there’s nothing coming and you want to turn right and the traffic lights is red it’s OK.
Also in Italy traffic lights are treated as just a suggestion of what you should do rather than an absolute 😉
