You can command the road all you want, but the graveyards are littered with cyclists and pedestrians who commanded the road. The problem is, you absolutely cannot even rely on every driver looking out their front window these days.
I've seen many looking out for a second, then looking at their phone for 4 to 5 seconds, before another quick glance up. These days you're up against some people who actually spend 20% of their time actually looking at the road.
I haven't heard anything yet about the most recent cyclist death, but I'd be very interested in the cause.
