In Europe (or at least in Spain) a very common ocurrence while driving is getting to a crossroad of slow traffic where you have to yield.

But traffic is heavy and you have no room to, for example, turn right.

So it's common practice to advance, little by little, until you're basically an obstacle and some other driver has no alternative than letting you in.

Otherwise, you'll spend much time waiting. To make thigns worse, the drivers behind you won't take this unending wait lightly either, so they'd get nervous and try to overtake you and all things get messsy.

How do these systems face this situation?

If the "other driver" is a German they would yell at you and cut you off. If a German driver would like to turn right in this particular situation they would set their indicator and wait until somebody lets them in -- which actually will happen rather quickly.

German drivers are full of contradictions (me too), it's quite heartwarming :D

If you do it rightly (softly, no brisk movements) in Spain, the other driver knows this is the way. No honking and no yelling
