As far as I am concerned, this was not an unavoidable accident, it's negligence on the part of the motorist, if as I believe from the reportarge, the cyclist were on the main road, and the crossroad was the minor road, then it's the motorist who should have stopped and made sure the way was clear, regardless of whether the oncoming traffic was motorised ,or not,or in this case 2 cyclist.
It doesn't matter that they were not wearing helmets, high Viz clothing, or displaying lights the motorist still hit them ,or one of them.
Is it not within the Highway code that there is a hierarchy of priority predestrians, with livestock, Cyclist, must have right of way at junctions or just crossing the road?
I am commenting, because I myself was a victim of a road collision, I obviously survived, I made not quite a full recovery, but it was at the time deemed serious enough for an Air Ambulance, so risk of life was a fair conclusion.
Whilst I do have sympathy for the driver to some extent, what with her being a presumably Medical doctor,, it doesn't exonerate her from blame, she may well have this on her conscience for the rest of her life, well I sure hope it does, but not in mean way.
Meanwhile, the Davenport family and friends have to live with this too, and I extend my sympathies to them.
This is an incident that cannot be reconciled unfortunately, it was an occasion that wasn't premeditated, but one that could have been avoided, there isn't an appropriate penalty or course of action to be taken against the driver, it's one of those things best described as an 'accident'.
I hope the Doctor involved has found a way to deal with this, it's as bad for her.
