I would like to know the rules for giving way of vehicles at signal-free intersections in SUMO

[Lemon007-kui]

I constructed a two-lane intersection with no signal light and found that some cars would stop to give way. I wanted to know what the rules were for this vehicle to give way.

Please have a look at the resources we already mentioned in #11222 . There it is explained how SUMO intersections work in general.
