I have a couple of drivers a year that decide they have to pass a car while approaching me head-on. Usually in places where there are relatively wide shoulders.
With me on the shoulder, they whiz by OK. I started waving my left hand to try to draw attention to myself, but don't think I've ever had a car slow down and pull back into their own lane.
The worst, however, was at Crater Lake. Narrow shoulderless road with unprotected dropoffs, and moderately rough pavement. I'd be descending at about 40 MPH in the middle of the lane when cars going uphill would decide they had to pass cyclists by lane splitting... except I felt I needed the whole lane due to road conditions. Was I going too fast? Maybe, but I still had cars that needed to pass me while I was descending at 40 MPH.
Of course, it is quite regular that vehicles will pass me going in the same direction I'm travelling, with oncoming traffic from the opposite direction. I've gotten used to it. Usually there is a bit of a weave, with the oncoming vehicles moving onto the shoulder to give a little more space.
I think the problem with this case is inadequate driver training. Ayasha Penfold was apparently a young driver (20?). The cyclist hit, John Durey was travelling faster than average (22 MPH), which decreases tolerances somewhat, and perhaps also makes them harder for drivers to predict. If he had been riding at 10 MPH, she might have safely passed the vehicle and returned to her lane before passing him.
What really is needed is more emphasis on care of passing "vulnerable road users", and to instill that into the core of all driver training.
I've suggested "Veto Questions" for drivers exams. If they miss a question about vulnerable road users, then it is an automatic fail.
I'm not sure what to do about drivers like Ayasha Penfold. I'm not convinced that a long prison term or huge fine would solve anything. Take away the driver's license for life if one wishes. Heck, it would be cheaper to buy here a very nice bicycle to ride than conducting the trial.
