Important! Who has to drive when meeting on the mountain?

Moin! What you don’t experience in road traffic :O :O. The following has happened: I ( 17 years, BF17 and a lot of experience in traffic, also have an A1 ) and mother drove up the mountain to our stray orchard. A very narrow (!) but yet concreted way. We ride normally up – and suddenly a LandRover comes to meet us. We both stop – behind me also another car stops. For a minute nothing does itself. Suddenly the man behind us gets out of the car. d goes to the SUV. Shortly afterwards he comes to us again, this time, and says: “You can’t talk to the xxx, he says he doesn’t drive away”. We wait another 4 minutes. It doesn’t hurt. Now my mother goes out and wants to talk to him – nothing happens. After about 4 more minutes we are then backwards ( I as a starter with a switchcar down a small path – in the rain!!! He can’t drive 10 meters backwards with his SUV? But I should go 50 meters backwards? Ahj a! Nice driving. So now to you: Who was right here now? Would I have had to go back or he? Ask for (fast) help! mfg
