I have actually read all the posts and think I understand everything. I reckon who's fault it is depends on which happened first out of:
(a) Joko couldn't see through the bus and didn't know whether anyone was overtaking it or not so assumed nobody was, and pulled out from the parking space
(b) Other Bloke got impatient and, though he thought that the road ahead of the bus was clear and he had enough room to overtake, didn't factor in that a parked car had just pulled out, so overtook the bus.
If he was already overtaking the bus when you pulled into the road it's your fault. You didn't know he was there so shouldn't have pulled into the space he was already aiming for. The fact that he was on the wrong side of the road is irrelevant. His way forward was clear when he started overtaking and you moved into it, unaware he was there.
If you had pulled out from your parking space, but he didn't see you and then overtook the bus, realising too late that there was nowhere for him to pull back into, then it's his fault.
In practice nobody knows which happend first so it is impossible to pin it on either one of you. You both could be to blame.
I hope you can see that (a) is entirely possible and so you are not entirely blameless?
