Unfortunately, the article mentions crashes but do's not give any details, as with most things in life, we only learn when things go wrong.
Further to my comment above, re stopping on roundabout;
There is nothing technically wrong with stopping on leaving a roundabout, or on a roundabout but it feels like asking for trouble.
Usually, if stopped on a roundabout that whole quadrant is stopped, on this roundabout, it can be just one vehicle in a position to leave and it cannot, life, and driving being what it is, the chances are there will be a vehicle following too close or intending to go to the next exit, a crash will result.
OK you would not be to blame but the insurers would tend to go for 50/50 'cause it's on a roundabout, and no matter whose at fault you still have a car that needs repair.
