When a vehicle would have to cross other paths (bike lanes etc), the priority is: pedestrian > cyclist > car. A bike lane crossing the road always has priority over cars unless signs say otherwise. At least that's how it works in Europe.
> who do you think those long stretches of roads are designed for if not cars?
The roads are usually intended for cars, yes. But they often aren't designed for safe, efficient travel with cars. Or anyone else, really. It's possible to design roads to be safe for everyone, but they often are the opposite. Just like planners still think that adding more lanes makes travel by car faster, when in reality it's long been known that it actually has the opposite effect.
