Eh, I can understand it though. Say you pull over to the right, have your right blinker on, someone behind you will not see the left light lit up, and if you are already stopped your brake lights aren't on.
With hazards, the full car is displayed.
If it's coming from a place of safety I think it's sensible. I so don't see it as particularly dangerous to adopt, other drivers slow down at most and see you and ignore you at least
That said, if we're coming from the place of safety, usually these instances the person should just fully park instead of pulling over with hazards.
