Dangerous car park markings?

[smelly garlic]

This afternoon I'm trying to find a space to park in the image related car park. Admittedly this car park is unfamiliar to me so I'm more cautious than usual; speed is <10 mph and I'm careful to observe the arrow markings on the main circuit. Despite my caution, a woman narrowly avoids 't-boning' my drivers side. Fortunately she managed to 'slam on' and stop just inside of the box junction - dirty looks suggesting I was at fault. IMO she was carrying too much speed and should have practised more caution, but that's not the point of the post.

I've since looked at the car park on google maps in an attempt to figure out who was at fault. Despite (IMO) the woman's poor observation and unsuitable speed, in my opinion the car park markings are bordering on negligent - requesting opinions on this. The yellow box junctions and the main circuit effectively form unmarked cross roads with no give way lines (effectively no one has priority?). The box junctions suggests that stopping is forbidden and one must exit onto the main circuit without giving way. I assume the purpose of the box junctions are to stop vehicles blocking the run to the single main exit, in which case the use of the box junctions are incorrect and give the wrong message.

Would it be correct to assume a 50/50 insurance claim if a collision had occurred? Frankly I'd be pissed off at the hassle and loss of NCB in the event of a collision, due to negligent road markings. I'm not usually one to complain, but I'm inclined to inform someone with responsibility that their car park is basically st.

Do you not have to give way to anything coming from the right as detailed in the Highway code?

That's the rule for a roundabout. Nobody has priority at unmarked x-roads.
