I'd go one further and say move well out into the road when approaching anything blind at speed, and check your back in advance to know if you can move even more out in a hurry. If you're uncomfortable with turning your head to check, you need a mirror. Hearing is not reliable to tell if there are cars there. Moving out into the middle of the road also signals any cars behind to hold it a minute and not pass. It also pisses off some drivers, but if you obviously and deliberately move out when needed, and back when the coast is clear, I think most drivers will see that you're doing for a reason.
It is tricky when things turn up un-expectedly, but it is your responsibility both as a driver and a cyclist to handle the unexpected, as it were. There could be an animal there, a car-crash, something that would force you to stop or move completely out of the way.
I'm not saying I never ride too fast to handle something like that, though
