It's annoying for the driver. It's worse for the bicyclist who has to worry about whether the driver have actually seen him as he comes barreling up from behind. But yeah, it's true that whoever designed shoulder-less roads was completely clueless to non-automobile transportation like biking, walking, or really even scooters that can't keep up with traffic. (Incidentally, the "coming up from behind" situation reminds me of one of my biggest annoyances as a motorcycle rider: people who come barreling up behind you when you are stopped at a light and then go hard on the brakes. They are apparently clueless to the fact that many motorbikes are rear-ended at stoplights because drivers fail to note the biker. The net effect is that you need to keep staring at your rear view mirrors ready to take off to avoid getting rear ended in case they actually haven't seen you. Really, the light is red. It won't hurt you to slow down gradually. So please everyone, don't do this.)
