That shift will happen all by itself. At some point, in a distant future, the price of the insurrance for human-driven cars will be so expensive that people because of that will choose a robot-driven car.

It is all about risk (the risk of the insurrance company loosing money) and an error prone and unpreditical human will be a considered high risk in that regard.

Will it though? Surely as driverless cars become viable the "I don't wanna do this, I actively don't care about doing it well" crowd will adopt them and insurance rates for everyone else will likely plummet.
