You have got to be kidding me. Show me any law in any European country stating that a motorist from a side road entering into another road, with no traffic controls, has right of way over a person already driving on the straight-through road. I seriously doubt that is the case anywhere. The way you're saying it, in this linked map, a motorist pulling out from the parking lot drive on the right side onto the main road would have right of way over a motorist driving from the bottom towards the top of the road in this aerial view, and that is simply wrong: https://goo.gl/maps/MZ38mKBke6F2

OP: where on the road/lane were you located? This is a good example where positioning yourself in the lane where a car driver would be can help with pull-outs like this. If you're off to the side or edge, it's easier for a motorist to misjudge your speed or not even see you at all. The motorist is looking for traffic approaching in the places where cars would normally be. So placing yourself in that location, with a bright flashing light if it's daylight, can help your chances with motorists seeing you and waiting if you have the right of way.

Of course none of that helps if the motorist is just generally a d-bag driver.
