I agree with what you say, I meant to establish that if there is a chain of blame, the driver would be first, then the person who allowed her to drive BEFORE even thinking about Tesla.
However, I agree that the buck appears to stop with the driver. Even if there was another vehicle involved on the wrong side of the road, sobriety would have perhaps avoided or mitigated the accident.
As for the comment about being 27, I recall saying at work that anybody under the age of 23 is basically a twat (a flippant comment meant in jest but ultimately 23 is not old enough to have enough wisdom not to be a twat). Every year that passes I add another year and I said it around 5 years old so the driver was basically a twat (being under 28) which is a shame as some wisdom may have saved her.
In 10 years time I will have added enough years to equal the age at which I made my bold proclamation which will make me a twat for saying it. There is always wisdom out there for people to glean.
