Yeah, this isn't just a thing to protect bicyclists, this is also about how to safely exit your vehicle with a lane of traffic next to you. Can't count the number of people over here (USA) that just blindly throw open their door and hope for the best.
I always check, and if I have to open my door with a line of traffic going by (there's some streets around here where traffic going by is literally endless) I open it a crack first, then open it only as much as I need to exit, and do the whole process slowly, and watch the approaching cars the whole time. I can't remember the last time I've ever seen someone else do that though.
