Well this differs between Sweden and UK
It doesn't though.
Just 'because' you think you have right of way, it isn't going to stop another road user if they make a mistake. In both clips you barrell through into two potentially dangerous situations expecting them to stop. The second clip, you were very lucky the taxi stopped, if he hadn't you'd be under the front wheels, air zound or not.
What you don't seem to have taken on, in this thread, is your riding style - it's been mentioned a few times. Yes the drivers were wrong, but your riding was plain stupid and arrogant, drivers won't always stop, be that because they weren't looking, or it's just too late.
You have mentioned you ride one way in cities, and another out in the country - why ? Not having had an accident 'yet' doesn't mean you are doing it right. Riding round like that, pushing through tiny gaps, weaving in and out, then flying through a junction, when it's clear a car is going to cross your path (rightly or wrongly) is just plain stupid. You are going to get it very wrong one day.
What's all this about sounding a horn, car or not. If you see a problem, you can slow down and anticipate it, then not need to use a horn - better all round for everyone as nobody gets worked up.
I'd take a chill pill if I was you. Don't go charging into possible situations just because you have right of way - it's a very quick way to get killed.
