I've often wondered how much preparation/study of the local laws does one need when driving in another country? If you lived in country A and were planning a holiday in country B, then yes I'd spend a bit of time googling their laws. But on a 2 week "coast to coast" road trip travelling through a dozen countries? I probably wouldn't bother. However, if I knew nothing about the UK "bike box" and was driving as a guest, something tells me it would be blindingly obvious what it was for. No? I mean, it's a symbol a bike surrounded by thick white lines. https://goo.gl/maps/zz1TvLM6fcv https://goo.gl/maps/zz1TvLM6fcv
